W32api Functions
Introduktion
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.

Note: This extension has been moved to the » PECL repository and is no longer bundled with PHP as of PHP 5.1.0.

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,
