CXVII. W32api Functions

Introducere

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().

Avertisment

Această extensie este EXPERIMENTALĂ. Comportamentul acestei extensii, incluzând numele funcţiilor şi orice altceva documentat despre această extensie ar putea fi schimbate fară un anunţ prealabil, intr-o viitoare versiune PHP. V-am avertizat, deci folosiţi această extensie pe riscul dv.

Necesităţi

This extension will only work on Windows systems.

Instalare

Nu este necesară o instalare a acestor funcţii, ele fac parte din PHP.

Configurare la rulare

Această extensie nu defineşte directive de configurare.

Tipuri de resurse

This extension defines one resource type, used for user defined types. The name of this resource is "dynaparm".

Constante predefinite

Aceste constante sunt definite de această extensie şi vor fi disponibile doar cînd extensia a fost fie compilată odată la instalarea PHP fie dacă extensia este încărcată dinamic la rulare.

DC_MICROSOFT (integer)
DC_BORLAND (integer)
DC_CALL_CDECL (integer)
DC_CALL_STD (integer)
DC_RETVAL_MATH4 (integer)
DC_RETVAL_MATH8 (integer)
DC_CALL_STD_BO (integer)
DC_CALL_STD_MS (integer)
DC_CALL_STD_M8 (integer)
DC_FLAG_ARGPTR (integer)

Exemple

This example gets the amount of time the system has been running and displays it in a message box.

Exemplu 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);
?>
