CV. W32api functionsIntroductie
This extension is a generic extension API to DLLs. This was originally
written to allow access to the Win32 API from PHP, although you can also
access other functions exported via other DLLs.
Currently supported types are generic PHP types (strings, booleans, floats,
integers and nulls) and types you define with w32api_deftype().
| Waarschuwing | Deze module is
EXPERIMENTEEL. Dat betekent, dat het gedrag van deze
functies, deze functienamen, in concreto ALLES dat hier gedocumenteerd is in
een toekomstige uitgave van PHP ZONDER WAARSCHUWING kan veranderen. Wees
gewaarschuwd, en gebruik deze module op eigen risico. |
Afhankelijkheden
This extension will only work on Windows systems.
InstallatieEr zijn geen handelingen nodig m.b.t. tot installatie
voor deze functies, deze maken deel uit van de kern van PHP. Configuratie tijdens scriptuitvoerDeze extensie gebruikt geen configuratie regels. Resource types
This extension defines one resource type, used for user defined types.
The name of this resource is "dynaparm".
Voorgedefineerde constanten
Deze constanten worden gedefineerd door deze extensie, en
zullen alleen beschikbaar zijn als de extensie met PHP is
meegecompileerd, of als deze dynamisch is geladen vanuit een script.
Voorbeelden
This example gets the amount of time the system has been running and
displays it in a message box.
Voorbeeld 1. Get the uptime and display it in a message box <?php
// Define constants needed, taken from
// Visual Studio/Tools/Winapi/WIN32API.txt
define("MB_OK", 0);
// Load the extension in
dl("php_w32api.dll");
// Register the GetTickCount function from kernel32.dll
w32api_register_function("kernel32.dll",
"GetTickCount",
"long");
// Register the MessageBoxA function from User32.dll
w32api_register_function("User32.dll",
"MessageBoxA",
"long");
// Get uptime information
$ticks = GetTickCount();
// Convert it to a nicely displayable text
$secs = floor($ticks / 1000);
$mins = floor($secs / 60);
$hours = floor($mins / 60);
$str = sprintf("You have been using your computer for:".
"\r\n %d Milliseconds, or \r\n %d Seconds".
"or \r\n %d mins or\r\n %d hours %d mins.",
$ticks,
$secs,
$mins,
$hours,
$mins - ($hours*60));
// Display a message box with only an OK button and the uptime text
MessageBoxA(NULL,
$str,
"Uptime Information",
MB_OK);

It should be noted that these functions are definately experimental.
I have got w32api_register_function() to work when using PHP4.2.0
RC4 from command line, but I have been unable to get them to work with
Apache1.3.24 (WinNT4), and they seem to cause Apache 2.0.35 (WinNT4) to
crash when they are used.

In order to use most (perhaps all?) of the win32 API while running with a
web server you have to give the server service permission to interact with
the desktop. This is especially noticeable with the given example, where
the script will try to display message boxes on the server's
display.
Keep in mind, however, that you should think hard about
the consequences of letting a web server interact with your desktop,
especially if you're not the only one using the web server.

The win32 api with PHP will output useless errors frequently but will still
work.
Use @w32api_register_function to suppress the useless errors.

"The behaviour of this extension -- including the names of its
functions and anything else documented about this extension -- may change
without notice in a future release of PHP."
The whole API
written here isn't working anymore as of version 4.3.0RC1. The W32API
Extension is completely rewritten.
If you want to use this
extension, than realize that in the new PHP releases your script might not
work anymore.???

I played a bit around with the W32API. Here is some code that actually
works with the current release of W32API.
The interface changed
completely, so all documentation about this extension is out-dated. While
the old release
just implemented "plain" functions, the
current version offers a class to handle all the API-related operations.
Additionally, functions are now registered using a SQL-like language
with a single string.
<?php
$api = new
win32;
/*
BOOL GetUserName(
LPTSTR lpBuffer, //
address of name buffer
LPDWORD nSize // address of size of
name buffer
);
Returns the current thread's username
"&" passes argument as "refrence" not as
"copy"
*/
$api->registerfunction("long GetUserName
(string &a, int &b) From advapi32.dll");
/*
DWORD GetTickCount(VOID)
Returns the ms the OS is
running
*/
$api->registerfunction("long GetTickCount () From
Kernel32.dll");
$len = 255; // set the
length your variable should have
$name = str_repeat("\0",
$len); // prepare an empty string
if ($api->GetUserName($name, $len)
== 0)
{
die("failed");
}
if (!($time =
$api->GetTickCount()))
{
die("failed");
}
echo "Username:
$name
\nSystemtime: $time
\n";
?>
GOOD LUCK
!!

I spend the last evening writing a more or less complete documentation of
what I figured out from the extensions source-code. Here we go:

This function/class WILL NOT work with APACHE2 on Win32.
It craches if
requested by apache.
if it will be executed with the command
line
eg. "php.exe myscript.php" works ;)
