本文實例講述了PHP編程實現腳本異步執行的方法。分享給大家供大家參考,具體如下:
php語言得用fsockopen()
函數,實現腳本異步運行,代碼如下
異步請求函數(用debug參數若為true則為用為調試,開啟調試可以看到異步的執行情況,但是失去異步的效果)

<?php header( "content-type:text/html;charset=utf-8" ); //error_reporting(0); //ini_set('html_errors',false); //ini_set('display_errors',false); $name = isset( $_POST [ 'name' ])? $_POST [ 'name' ]: '' ; $pwd = isset( $_POST [ 'pwd' ])? $_POST [ 'pwd' ]: '' ; echo $name . $pwd ; echo 'success ok' ; die ; ?> |
使用實例:
[運行的main.php主腳本文件]

$data = array ( 'name' => 'guoyu' , 'pwd' => '123456' ); $url = 'http://localhost/test/other.php' ; request_by_fsockopen( $url , $data ,true); //把應用B的用戶表異步-同步數據 |
[導步執行文件other.php]
在other.php中便可以用$_POST接收main.php提交過來的參數,從而進行下一步操作
希望本文所述對大家PHP程序設計有所幫助。
