I got a simple way to let php5 work with oracle 9i seamlessly.

    According to the normal case,it reports a error not to find libclntsh while compiling the php5.You could do a soft link as follow:

  ln -s $ORACLE_HOME/lib/libclntsh.so.9.0 $ORACLE_HOME/lib/libclntsh.so 



   After that, you recompile the php5 and it'sl ok now.

I had a hard time getting Oracle to work with the new PHP5 - here is a short step by step guide that may be usefull to others..



Oracle installation problems and workarounds for Fedora2 and Debian.. 



1) Get the oracle client stuff and put it into /usr/lib/oracle..

My output from "ls -R /usr/lib/oracle/"

/usr/lib/oracle/:

10.1.0.2

/usr/lib/oracle/10.1.0.2:

client

/usr/lib/oracle/10.1.0.2/client:

lib

/usr/lib/oracle/10.1.0.2/client/lib:

classes12.jar  libclntsh.so  libclntsh.so.10.1  libnnz10.so  libocci.so.10.1  libociei.so  libocijdbc10.so  ojdbc14.jar



2) Set the ORACLE environment vars

export ORACLE_HOME=/usr/lib/oracle/10.1.0.2/client/

export LD_LIBRARY_PATH=/usr/lib/oracle/10.1.0.2/client/lib

export NLS_LANG=DANISH



3) Get the oracle source files 

nzerror.h  oci1.h    ociap.h   ocidef.h  ocidfn.h   oci.h    ocikpr.h    ori.h  oro.h nzt.h oci8dp.h  ociapr.h  ocidem.h  ociextp.h  ocikp.h  oratypes.h  orl.h  ort.h



4) edit the file oci.h and add a line in the top below the comments

#define OCI_NLS_CHARSET_ID 0



5) Copy the oracle source files (.h and .c) files to 

php-5.0.0/ext/oci8/ and also copy them to php-5.0.0/main/



6) Goto the php-5.0.0. dir and do a ./configure --with-oci8 and other stuff you need..



7) make install



8) Add these lines to /etc/rc.d/initd/httpd



export LD_LIBRARY_PATH=/usr/lib/oracle/10.1.0.2/client/lib

export NLS_LANG=DANISH

export ORACLE_HOME=/usr/lib/oracle/10.1.0.2/client/lib

export LD_LIBRARY_PATH=/usr/lib/oracle/10.1.0.2/client/lib

export TZ=GMT

export NLS_DUAL_CURRENCY='.'



# Notice the line export NLS_DUAL_CURRENCY='.' is needed to get the stuff to run correctly on Fedora 2 .. otherwise you get a nasty misleading error about invalid username or password!.

Oracle Client 9i on Windows XP (2000) plus IIS, plus Oracle RDBMS on remote server.

The bad thing that nothing will be working on windows-based comp. until you will not change the proper permissions on some files.



Fist you will need to set environment

ORACLE_SID (not necessary)

ORACLE_HOME (necessary)

TNS_ADMIN (necessary).



Second: add user IUSR_user read permission on the directory pointed by TNS_ADMIN. The same user permission r/x on the file orannts9.dll in ORACLE_HOME\bin (this was finded experimentally). After this instructions  ora_logon or ocilogon will be executed without deadly error codes ORA-12154 or ORA-12538.

More on the header files needed to compile PHP...



I installed the client side of Oracle 9i for Linux in different configurations, and could not get the oci*.h files that PHP requires for compilation.  So in the end, I searched for them through the jar files, and here's the result:



As you probably know, the Oracle for Linux package comes in three download files, or three disks.  Go to this path:



/path/to/disks/Disk2/stage/Components/oracle.rdbms.oci



The rest of the directories are based on the release number, so they may look a little bit different but you get the picture:



9.2.0.1.0/1/DataFiles/public.1.1.jar



and use "jar xf" to extract it and grab the header files.  Copy them to:



$ORACLE_HOME/rdbms/demo



And your make will work.  Since this wasted half of a day of mine (even after going through lots of comments on the Internet) I hope it saves somebody else's time...

To make sure my oracle get's rolledback when my script once in a while dies or I make a mistake (statements are terminated with ";"...). I use this construction. Because if it isn't rolled back and you use plogon, other oracle connections might hang, until the apache process that ran the failed script is terminated, and therefore releases the connection and gives the implicit rollback.



The use of a shutdown_function:



$oracle = ora_plogon("user/pass@db", "") or die("Can't connect to db");

$cursor = ora_open($oracle);

ora_commitoff($oracle);



function ora_shutdown() {

  global $oracle;

  global $cursor;

  ora_rollback($oracle);

  ora_close($cursor);

  ora_logoff($oracle);

}



register_shutdown_function(ora_shutdown);

Here is my little but very very useful tutorial :-)



CONNECTION : (in connect.php)

<?php

$ora_conn = ora_logon("databaseName@service","pass");

?>

-----------------------------

DISCONNECT : (in disconnect.php)

<?php

ora_logoff($ora_conn);

?>

-----------------------------

In each page, you must include both files

<?php

include("connect.php");

blah blah

include("disconnect.php");

?>

-----------------------------



Now the hard... SELECT ! (in select.php)

<?php

// Comment the line error_reporting if you want to

// debug your code - for example the "NO DATA FOUND"

// when no result. Oracle returns this like an error.

error_reporting(0);



// Create an array, a cursor, count number of cols,

// perform the fetch and insert in the array.

$results = array();

$ora_cur = ora_do($ora_conn, $query);

// Don't panic, the $query will be set, wait a bit :)



if ($ora_cur)

{

  // Number of cols

  $numCols = ora_numcols($ora_cur);



  // Put the first line in the array...

  $row = array();

  for($i=0; $i<$numCols; $i++)

  { // for each column

    $row[ora_columnname($ora_cur,$i)] = ora_getcolumn($ora_cur,$i);

  }

  array_push($results,$row);



  // "Fetch" all records, one by one, and create an array for each one.

  // Each array is "pushed" in the $results array.

  while (ora_fetch($ora_cur))

  { // for each record

    $row = array();

    for($i=0; $i<$numCols; $i++)

    { // for each column

      $row[ora_columnname($ora_cur,$i)] = ora_getcolumn($ora_cur,$i);

    }

    // Push $results

    array_push($results,$row);

  }

}

// Now turns error_reporting on. Comment this line if you want

// to see "NO DATA FOUND" warnings.

error_reporting(1);

?>

--------------------------



And now let's enjoy with this simple page !! :)



<?

include("connect.php");

echo "blah blah";

$query = "select NAME, AGE from people where...";



include("select.php");



// Browse $results array and display results :

if (count($results)) // if no "NO DATA FOUND"

{

 reset($results);

 while($res=each($results))

 {

/*

 $res is like :

array(0 => array('NAME' => 'Sylvain', 'AGE' => '21'),

      1 => array('NAME' => 'Somebody','AGE' => '888'));

 */

  echo $res[1]['NAME']; // name

  echo $res[1]['AGE']; // age

  // ALLWAYS write in uppercase !

 }

}

else // NO_DATA_FOUND :(

{

 echo "There's nobody in your database :D";

}



echo "blah blah and again blah";

//...another queries

$query = "...";

include("select.php");...



include("disconnect.php");

?>



----------------------

Another queries (insert, update...) are simpler. Let's see :)

<?php

include("connect.php");

$query = "UPDATE people SET url=' where name='Sylvain'";

include("query.php");

include("disconnect.php");

?>



and query.php is :

<?php

$cursor = ora_open($ora_conn); // Create a cursor

if($cursor) // if created

{

  // Parse query

  $resultat = ora_parse($cursor,$query);

  $resultat = ora_exec($cursor); // Execute

  $a=ora_commit($ora_conn); // perform COMMIT

  $b=ora_close($cursor); // close cursor

}

else

{ // Write an error message

  echo "oh, oh ! problem...";

}

?>



Now enjoy using it !

I got error messages when compiling after configured php-4.3.4, apache-1.3.29 and with Oracle client 9.2.0 (MySQL also) installed. 



My configure command was:



./configure \

--with-mysql \

--with-oracle=$ORACLE_HOME \

--with-oci8=$ORACLE_HOME \

--enable-sigchild \

--enable-track-vars \

--with-xml \

--with-apache=../apache_1.3.29 \

--enable-exif



What made the error was lack of some headers (ociextp.h, oci.h...etc) These headers are located in the following dirs:



$ORACLE_HOME/rdbms/public

$ORACLE_HOME/rdbms/demo



Just install the Oracle developement kit in the Oracle database folder, I suggest using custum selection if passing php compilation is all yo want:)



One can either make sure these two directories are included or just copy the *.h into php-4.3.4/include

Ok. Considering it took me about three hours to find the answer to this: 



Running a stored procedure in Oracle 8i + PHP4 (explicitly).



$sql = "begin procedure_name($required_variables_string); end;";



... execute code here...



but your string should look like what is given above.

For example, if I was going to execute the following: 

$sql = "SELECT * from some_table"; looks like straight SQL, vs the one above which looks more like a PL/SQL block. 



A bit gay in my opinion, but this is my 2c for those who might need to know how to execute a stored procedure using PHP.

A simple function



# list query in array

#

# $conn: connection

# $query: query_string

#

# return: $templist[$row][$column]=$value;



function get_query($conn,$query){

 $cursor = ora_open($conn);

 ora_parse($cursor, $query) or die;

 ora_exec($cursor);

 $numcols = ora_numcols($cursor);

 $i=0;

 while(ora_fetch($cursor)){

  for($column=0; $column < $numcols; $column++){ 

   $colname = trim(ora_columnname($cursor, $column));

   $data = trim(ora_getcolumn($cursor, $column));



   $templist[$i][$colname]=$data;

  }

  $i++;

 }

 return $templist;

}



i.e.:



$conn = ora_plogon( "user", "passwd")or die; 



$cursor = ora_open($conn); 



ora_commitoff($conn); 



$query = "SELECT * FROM table"; 



$result=get_query($conn,$query);



for($i=0;$result[$i];$i++){

 echo $result[$i][column];

}

The following function returns more detailed information about the columns of a table. It returns an array of hashes, with columnname, type, size, precision, scale, nullable, comments and constraints.





    function columninfo($cursor, $table) {

        $query .= "  user_tab_columns.data_scale,";


        $query .= "  user_tab_columns.nullable,";


        $query .= "  user_col_comments.comments,";


        $query .= "  (SELECT";

Usefull system table: all_tab_comments





It shows all tables/views that you can read, including a lot of other usefull system tables like user_objects, user_tab_columns, user_constraints.

If you use Oracle and PHP on the same computer, you can start only "dbstart" for runing PHP with Oracle and don't start "lsnrctl" maybe for security reason.

Here is a code sample that I used on NT 4.0 running Apache/Oracle 8.1.6/PHP 4.0 : I used it to connect to the sample scott-tiger schema EMP table. It is pretty much a hack, but I hope it helps you.





<?php





putenv('ORACLE_SID=DMEARLS.WORLD');


putenv('ORACLE_HOME=d:\oracle\ora81');


putenv('TNS_ADMIN=d:\oracle\ora81\network\admin');


$foo=exec("echo %ORACLE_SID%");


echo $foo;


//Set("ORACLE_SID=DMEARLS.WORLD");


//Set("ORACLE_HOME=D:\oracle\isuites");


       //$db = "dmearls.world";


       // create connection


    //  $connection = ora_logon("scott","tiger")


      $connection = OCILogon("scott","tiger","dmearls.world")


               or die("Couldn't logon to database.");





       // create SQL statement


       $sql = "SELECT ENAME, SAL


               FROM EMP


               ORDER BY SAL";


echo "<br>";


echo $connection;


echo "<br>";


echo $sql;


echo "<br>";





       // parse SQL statement


       $sql_statement = OCIParse($connection,$sql)


               or die("Couldn't parse statement.");


echo $sql_statement;


       // execute SQL query


       OCIExecute($sql_statement)


               or die("Couldn't execute statement.");





       // get number of columns for use later


       $num_columns = OCINumCols($sql_statement);


echo "<br>";


echo $num_columns;


       // start results formatting


       echo "<TABLE BORDER=1>";


       echo "<TR>


             <TH>Name</TH>


             <TH>Salary</TH>


             </TR>


             ";





       // format results by row


       while (OCIFetch($sql_statement)) {


               echo "<TR>";


               for ($i = 1; $i < $num_columns; $i++) {





                       $column_value1 = OCIResult($sql_statement,$i);


                       $column_value2 = OCIResult($sql_statement,$i+1);


                       //echo $i;

...and with the dawning of the new year, my TNS problem is gone. I've been having trouble connecting to a remote db server from Linux running Apache/PHP+Oracle. I'd set the ORACLE_HOME and ORACLE_SID (although, I'm not sure if it cares about the SID when connecting via SQL*Net/Net8) with no luck. The environment variable that does the trick is TNS_ADMIN. (I saw a mention of this on phpbuilder and thought I'd mention it here)<br>


Set TNS_ADMIN to the directory with your tnsnames.ora file and see if that dosen't help the TNS unable to connect problems<p>





setenv("TNS_ADMIN=/opt/oracle/product/8.1.5/network/admin");





... does the trick for me.

ora_numrows($cursor) only works when there's  an ora_fetch before. it will return the number of rows resulting from the query.

If you ever come accross trying to store non ASCII characters over PHP, ORACLE will probably not store thos characters properly, allthough you've set NLS_LANG and ORA_NLS33 in the Oracle User's ENV. the trick is to set these environment at Apaches' Startup. putenv and getenv didn't help at all. ) i meant apache's init script of course, provided you've got a SYS V style UNIX.

Using "@dbname" in ora_logon/ora_plogon will force a SQL*Net connect, even if the database is on the local host.  It's more efficient to use the ORACLE_SID environment variable.





putenv( "ORACLE_SID=dbname" );


$handle = ora_plogon( "SCOTT",  "TIGER");

Oracle Example


Prerequisites:





 You need to know the values of the following environment variables:





ORACLE_HOME


This is the path to your Oracle installation directory. It is usually defined in the UNIX login script of your oracle user and all Oracle client users.





ORACLE_SID


This is the name of the database instance you want to connect to. It is also defined in the UNIX environment of your oracle user and all Oracle client users.





Find out the values of these variables by loggin in as a user who can connect to the database in question with sqlplus. Then type at your Unix shell prompt:





prompt> echo $ORACLE_HOME


/opt/oracle/oracle/8.0.3


prompt> echo $ORACLE_SID


ORACLE





A simple PHP script using ora_* functions





<?php


  putenv("ORACLE_SID=ORACLE");


  putenv("ORACLE_HOME=/opt/oracle/oracle/8.0.3");





  $conn = ora_login("scott", "tiger");


  $curs = ora_open($conn);





  ora_commitoff($conn);





  $query = sprintf("select * from cat");





/* Long version */


/*


  ora_parse($curs, $query);


  ora_exec($curs);


  ora_fetch($curs);


*/


/* Short Version */


  ora_do($conn, $query);





  $ncols = ora_numcols($curs);


  $nrows = ora_numrows($curs);


  printf("Result size is $ncols cols by $nrows rows.<br>");





  for ($i=0; $i<$ncols; $i++) {


    printf("col[%s] = %s type[%d] = %s<br>",


      $i, ora_columnname($curs, $i),


      $i, ora_columntype($curs, $i));


  }





  for ($j=0; $j<$nrows; $j++) {


    for ($i=0; $i<$ncols; $i++) {


      $col = ora_getcolumn($curs, $i);


      printf(&quotval[%d, %d] = %s * ", $j, $i, ora_getcolumn($curs, $i);


    }


    printf("<br>");


  }
