W32api Functions
Introduction
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().
Note: This extension has been moved to the » PECL repository and is no longer bundled with PHP as of PHP 5.1.0.
Varoitus! Tämä laajennus on EKSPERIMENTAALINEN. Tämän laajennuksen ominaisuudet, käyttäytyminen sekä funktioiden nimet ja parametrit voivat muuttua varoituksetta seuraavissa PHP versioissa.
Requirements
This extension will only work on Windows systems.
Installation
Näiden funktioiden käyttö ei vaadi erillisten ohjelmien asentamista; ne toimitetaan PHP:n mukana.
Runtime Configuration
Tämä laajennus ei määrittele yhtäkään direktiiviä php.inissä.
Resource Types
This extension defines one resource type, used for user defined types. The name of this resource is "dynaparm".
Predefined Constants
The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.
Examples
This example gets the amount of time the system has been running and displays it in a message box.
Example#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);
?>
