XII. Funkce pro pr�ci s CURL, Client URL Library

�vod

PHP podporuje libcurl, knihovnu vytvo�enou Danielem Stenbergem, kter� umo��uje spojen� a komunikaci s mnoha r�zn�mi typy server� v mnoha r�zn�ch typech protokol�. libcurl v sou�asn� dob� podporuje http, https, ftp, gopher, telnet, dict, file a ldap protokoly. libcurl tak� podporuje HTTPS certifik�ty, HTTP POST, HTTP PUT, FTP uploady (toto umo��uje i ftp extenze PHP), HTTP formul��ov� uploady, proxy, cookies a user+password autentikaci.

Tyto funkce byly p�id�ny v PHP 4.0.2.

Po�adavky

Pokud chcete pou��vat CURL funkce, mus�te nainstalovat . PHP vy�aduje pou�it� CURL 7.0.2-beta nebo vy��. S verzemi CURL star��mi ne� 7.0.2-beta PHP nebude pracovat. V PHP 4.2.3 budete pot�ebovat CURL 7.9.0 nebo vy��. Od PHP 4.3.0 budete pot�ebovat CURL 7.9.8 nebo vy��. PHP 5.0.0 bude nejsp� pot�ebovat CURL verze v�t�� ne� 7.10.5

Instalace

D�le mus�te PHP zkompilovat s volbou --with-curl[=DIR], kde DIR je um�st�n� adres��e obsahuj�c�ho lib a include adres��e. V "include" adres��i by m�l b�t adres�� pojmenovan� "curl", kter� by m�l obsahovat soubory easy.h and curl.h. V adres��i "lib" by m�l b�t soubor pojmenovan� "libcurl.a". Po��naje PHP 4.3.0 m��ete PHP nakonfigurovat tak, aby po��valo CURL pro url-streamy pomoc� direktivy --with-curlwrappers.

Pozn�mka pro Win32 u�ivatele: Pro zaji�t�n� funkce tohoto roz��en� ve Windows mus�te zkop�rovat knihovny libeay32.dll a ssleay32.dll z adres��e DLL distribuce PHP/Win32 do adres��e SYSTEM. (Nap�.: C:\WINNT\SYSTEM32 or C:\WINDOWS\SYSTEM)

P�eddefinovan� konstanty

Tyto konstanty jsou definov�ny t�mto roz��en�m a budou k dispozici pouze tehdy, bylo-li roz��en� zkompilov�no spole�n� s PHP nebo dynamicky zavedeno za b�hu.

P��klady

Pokud m�te PHP zkompilovan� s podporou CURL, m��ete za��t pou��vat CURL funkce. Z�kladn� principem t�chto funkc� je, �e pomoc� curl_init() inicializujete CURL session, potom pomoc� curl_exec() nastav�te hodnoty p�enosu a nakonec session zav�ete pomoc� curl_close(). N�sleduje uk�zka, kter� vyu��va CURL funkce ke sta�en� homepage PHP do souboru:
P��klad 1. Pou�it� CURL extenze ke sta�en� homepage PHP

<?php $ch = curl_init ("http://www.example.com/"); $fp = fopen ("example_homepage.txt", "w"); curl_setopt ($ch, CURLOPT_FILE, $fp); curl_setopt ($ch, CURLOPT_HEADER, 0); curl_exec ($ch); curl_close ($ch); fclose ($fp); ?>

Obsah
curl_close -- Zav��t CURL session
curl_copy_handle -- Copy a cURL handle along with all of it's preferences
curl_errno -- Return the last error number
curl_error -- Return a string containing the last error for the current session
curl_exec -- Prov�st CURL session
curl_getinfo -- Get information regarding a specific transfer
curl_init -- Inicializovat CURL session
curl_multi_add_handle -- Add a normal cURL handle to a cURL multi handle
curl_multi_close -- Close a set of cURL handles
curl_multi_exec -- Run the sub-connections of the current cURL handle
curl_multi_getcontent -- Return the content of a cURL handle if CURLOPT_RETURNTRANSFER is set
curl_multi_info_read -- Get information about the current transfers
curl_multi_init -- Returns a new cURL multi handle
curl_multi_remove_handle -- Remove a multi handle from a set of cURL handles
curl_multi_select -- Get all the sockets associated with the cURL extension, which can then be "selected"
curl_setopt -- Nastavit parametr CURL transferu

btw, CURLOPT_HTTPHEADER expects an array:



$myHeader = array(

    "MIME-Version: 1.0",

    "Content-type: text/html; charset=iso-8859-1",

    "Content-transfer-encoding: text",

);

    

curl_setopt($ch, CURLOPT_HTTPHEADER, $myHeader);



(hope this saves someone several hours of...)

A note of warning for PHP 5 users: if you try to fetch the CURLINFO_CONTENT_TYPE using curl_getinfo when there is a connect error, you will core dump PHP. I have informed the Curl team about this, so it will hopefully be fixed soon. Just make sure you check for an error before you look for this data.

In recent versions of php, CURLOPT_MUTE has (probably) been deprecated. Any attempt of using curl_setopt() to set CURLOPT_MUTE will give you a warning like this:



PHP Notice:  Use of undefined constant CURLOPT_MUTE - assumed 'CURLOPT_MUTE' in ....



If you wish tu silence the curl output, use the following instead:



    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);



And then,



    $curl_output=curl_exec($ch);



The output of the curl operation will be stored as a string in $curl_output while the operation remains totally silent.

Multipart form uploads (ie simulating the upload of files from a browser form) is surprisingly easy, yet hard to find information on.... hope this changes that. 



$postData = array();



//simulates <input type="file" name="file_name">

$postData[ 'file_name' ] = "@test.txt";

$postData[ 'submit' ] = "UPLOAD"; 

        

$ch = curl_init();



curl_setopt($ch, CURLOPT_URL, $url );        

curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);

curl_setopt($ch, CURLOPT_POST, 1 );



//seems no need to tell it enctype='multipart/data' it already knows

curl_setopt($ch, CURLOPT_POSTFIELDS, $postData );



$response = curl_exec( $ch ); 



//where test.txt is a file in the same directory!

If you have upgraded to using thread safe PHP (with apache 2 MPM=worker) note that

CURLOPT_COOKIEJAR / CURLOPT_COOKIEFILE both need an absolute path set for the cookie file location and no longer take a relative path. 

(As before, also remember to have set correct permissions to allow a writeable cookie file/dir by apache)

It took me quite some to to figure out how to get Curl (with SSL), OpenSSL and PHP to play nicely together.



After reinstalling MS-VC7 and compiling OpenSSL to finally realise this was'nt nesscary.



If your like me and like *Nix systems more than Windows then you'll most probly have similar problems.



I came across this, on a simple google with the right keywords.







I read thru that and found my mistake.



Its just a small list of notes, I found them to be the best I've found on the subject and the most simplist.



Dont forget to add a simple line like this into your scripts to get them working on Win32.



<?php

if($WINDIR) curl_setopt($curl, CURLOPT_CAINFO, "c:\\windows\\ca-bundle.crt");

?>



Last note: ca-bundle.crt file is located in the Curl download. I stored mine in the windows directory and apache/php can access it fine.



All the best and I hope this helps.

You can request (and have deflated for you) compressed http (from mod_gzip or ob_gzhandler, for instance) by using the following:



curl_setopt($ch,CURLOPT_ENCODING , "gzip");



This seems to work fine with the latest php (4.3.4) curl (7.11.0) and zlib (1.1.4) under linux.  This is much more elegant than forcing the Accept-Encode header and using gzdeflate on an edited result.

I know that many people suffer from cURL when trying to send XML data. I solved this problem and want to share it with you:





I was trying to send SMS messages with a SMS service provider. They gave me the following ASP code, where you send data as XML and receive a response in XML as well:





url = "";


xmldata ="<XMLtag1>many other tags, data here</XMLtag1>";


Set ob = Server.CreateObject("Msxml2.XMLHTTP")


ob.Open "POST",url,false


ob.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"


ob.Send xmldata


...then recieve code was here...





This is done in PHP using cURL library in this way:





<?php


$XPost = "<XMLcontent>sameas above</XMLcontent>"


$url = "..same URL as above.."; 


$ch = curl_init();    // initialize curl handle 


curl_setopt($ch, CURLOPT_URL,$url); // set url to post to 


curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable 


curl_setopt($ch, CURLOPT_TIMEOUT, 4); // times out after 4s 


curl_setopt($ch, CURLOPT_POSTFIELDS, $XPost); // add POST fields 


$result = curl_exec($ch); // run the whole process 


echo $result; //contains response from server


?>





Some say that you should use CURLOPT_CUSTOMREQUEST, CURLOPT_HTTPHEADER and etc. to perform this task , as you can see you don't need those at all.





Hope it will help those who tries to simulate Msxml2.XMLHTTP or simply try sending XML data over PHP.

Here's how I was able to post arrays using Curl:



$array_of_vars[]="var1";

$array_of_vars[]="var2";

$array_of_vars[]="var3";

$array_of_vars[]="var4";



$submit_url = "";

$formvars["feild1"] = "feild1";



for ($i=0;$i<sizeof($array_of_vars);$i++)

    $formvars["array_of_vars[$i]"] = $dna[$i];



    

// init curl handle

$ch = curl_init($submit_url);

curl_setopt($ch, CURLOPT_VERBOSE, 1);

curl_setopt($ch, CURLOPT_HEADER, 1);

curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1); 

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_POSTFIELDS, $formvars);



// perform post

$rr=curl_exec($ch);

echo $rr;

curl_close($ch);

The following scripts show how to post form to a web server via https.  I modified rodrigo posting because it did not work for me on IIS5.

<?php

    $url = 'https://www.yourserver.com/yourrequest;

    $params = "name=your_name&[email protected]";

    $user_agent = "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";



    $ch = curl_init();

    curl_setopt($ch, CURLOPT_POST,1);

    curl_setopt($ch, CURLOPT_POSTFIELDS,$params);

    curl_setopt($ch, CURLOPT_URL,$url);

    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,  2);

    curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);

    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);  // this line makes it work under https



    $result=curl_exec ($ch);

    curl_close ($ch);



    echo("Results: <br>".$result);

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_POST,1);

    curl_setopt($ch, CURLOPT_POSTFIELDS,$params);

    curl_setopt($ch, CURLOPT_URL,$_url);

    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,  2);

    curl_setopt($ch, CURLOPT_USERAGENT, $defined_vars['HTTP_USER_AGENT']);

I managed to use curl to retrieve information from severs on ports other than 80 or 443 (for https) on some installations but not on all. 

If you get an "CURLE_COULDNT_CONNECT /* 7 */" error, try adding the port : (for example)

curl_setopt($ch, CURLOPT_PORT, $_SERVER['SERVER_PORT']);

IMHO the example code is somewhat confusing; the fopen() and fclose() are not needed at all, AFAICT.



By default the resulting data/page of the external server is just printed out. To assign the result of the curl session to a variable, one can use

- output buffering (see ob_start(), ob_get_contents())

- curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

With the latter, the result of curl_exec is the actual data instead of a boolean.

Here's a little code snippet if you need the last-modified-time for a remote file as filemtime() does not work on those. :)



$modified = "";

function read_header($ch, $header)

{

    global $modified;

    $length = strlen($header);

    if(strstr($header, "Last-Modified:"))

    {

        $modified = substr($header, 15);

    }

    return $length;

}



function last_mod($remote_file)

{

    global $modified;

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $remote_file);

    curl_setopt($ch, CURLOPT_HEADER, 1);

    curl_setopt($ch, CURLOPT_NOBODY, 1);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'read_header');



    $headers = curl_exec ($ch);

    curl_close ($ch);

    return $modified;

}



use something like

    echo strtotime(last_mod(""));

to get the time as an Unix timestamp or

    echo last_mod("");

to get the gmdate()-like time.

If you want to Curl to follow redirects and you would also like Curl to echo back any cookies that are set in the process, use this:



curl_setopt($ch, CURLOPT_COOKIEJAR, '-');



'-' means stdout

if you need to install curl on a windows system, this has the best explanation:

bharris at spro dot net
26-Feb-2003 12:58


For Win2000: To get the 4.3.1 curl dll to work with https you now need to download the latest win32 curl library from  and snag the ca-bundle.crt file from the lib directory.  Place this somewhere handy on your webserver.



Then in your PHP script, add the following setopt line to the rest of your curl_setopt commands:



curl_setopt($ch, CURLOPT_CAFILE, 'C:\pathto\ca-bundle.crt')



This worked for me and allowed me to discontinue using the CURLOPT_SSL_VERIFYPEER set to zero hack.

When using cURL to do posts, make sure you actually specify the CURLOPT_POSTFIELDS option. Not doing so seems to make PHP core (and apache as well if you're running it through there).

If anybody has problems with getting new curl working with older version of php then ...



I got stuck with installing curl-7.10.2+php 4.0.6 or better said configuring PHP with mentioned version of curl.



After some hopeless attempts to configure curl support into PHP I saw an error message:



"checking for cURL greater than or equal to 7.8... ./configure: line 11725: test: 070a02: integer expression expected"



after which configure said: "configure: error: cURL version 7.8 or later is required to compile php with cURL support"



On the mentioned line "test" is used to compare verion from curl-sonfig with preset value 70800 but ... test expects both values to be integer. From verson 7.8 curl outputs its version in hex...



I did'nt had the time to think about fixing this - I just deleted lines responsible and got curl working :)

I wanted to import an https Web pages thanks to fopen("https://xxx", "r") or fsockopen but as far as I read, it was only possible with cURL extension (to get these functions worked with https, we have to wait the PHP 4.3 release, TBC) , so I installed it and it worked. It is quite easy, but I spend to much time on it:

First of all, here is the most important: WE DON'T NEED to compile anything to get curl worked. All the extensions that we need are already in the PHP 4.2.3 zip. So here are the instructions and links to get Apache + PHP + CURL work properly:



Downloads:

=> Apache Web server with Openssl included:

    Apache_1.3.26-Mod_SSL_2.8.9-OpenSSL_0.9.6d-WIN32.zip



=> PHP 4.2.3 for Windows:

   



=> Optional: Openssl zip to get libeay32.dll and ssleay32.dll (I didn't need them because I used those stored in PHP zip)

 OpenSSL-0.9.6d-win32_RAR3_Archive_.rar



Installs:

=> Unzip Apache in Program Files folder(there should be no problem with the blank in the path):



=> Follow those instructions:  . I didn't exactly do what they wrote but it helped a lot. I created the test certificat thanks to this link in order to test my Apache server with SSL.



=> Configure httpd (easy to find on the Web) and test Apache before going on, it avoids problems.

   I just changed the Port from 80 (http) to 443 (https) in httpd, I only wanted to perform https.

   I didn't try to get the both working together. 



=> Unzip PHP in C:\Php path (don't install it in Program Files folder, you would have troubles because of the blank this time...) 



=> Configure PHP :  #install.windows.manual

   WARNING: php.ini MUST be stored into the c:\winnt folder and the dlls must be stored into the c:\winnt\system32 folder.



=> Test it with Apache and phpinfo() function.



cURL:

To add cURL extension, YOU DON'T NEED to compile anything.

All the extensions that you need are in the C:\php\extensions folder. To add cURL or any other extensions:



=> Have the libeay32.dll and ssleay32.dll in the system32 folder (already done if you installed PHP)



=> Copy all dlls from php/dll/ folder to winnt/system32/ (libeay32.dll and ssleay32.dll are already there if you followed

   the previous steps)



=> Remove the ";" in front of extension=php_curl.dll in php.ini.



Those instructions come from:  #install.windows.extensions



And it should work, just test it with curl functions into your php script.

Using the customrequest for a complete post is wrong. Libcurl will add a partial url, the http version and the standard headers after the post data - while this works with a non-persistent connection and an apache web server, it may fail under different conditions

If you want to write your entire HTTP request without use any other CURL functions like CURLOPT_POST specify it within a curl_setopt ($ch,CURLOPT_CUSTOMREQUEST , $req) line; 


Where $req looks like (let me imagine a POST request...):





POST /destination/script HTTP/1.1


Content-length: xxx


Content-type: text/xml


host: yourhost


accept: */*


accept-encoding: gzip, deflate


accept-language: en-us


connection: close; Keep-Alive


...


your POST data


...








CURLOPT_CUSTOMREQUEST is not documented?!? but it's useful and amazing!

I used to download www pages to my script and one of the pages was different in MS explorer and different, when I downloaded it. Namely, information, I was really interested in was missing. That was because the server on the other bank of the river was looking at who is downloading the page. Everything got fixed when I pretended I was MSIE. It is done with curl. Here is a function, that you may use in similar situation





function download_pretending($url,$user_agent) {


   $ch = curl_init();


   curl_setopt ($ch, CURLOPT_URL, $url);


   curl_setopt ($ch, CURLOPT_USERAGENT, $user_agent);


   curl_setopt ($ch, CURLOPT_HEADER, 0);


   curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);


   $result = curl_exec ($ch); 


   curl_close ($ch);


   return $result;


}
