本文實(shí)例講述了PHP編程實(shí)現(xiàn)腳本異步執(zhí)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(shù),實(shí)現(xiàn)腳本異步運(yùn)行,代碼如下
異步請求函數(shù)(用debug參數(shù)若為true則為用為調(diào)試,開啟調(diào)試可以看到異步的執(zhí)行情況,但是失去異步的效果)

<?phpheader("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(shí)例:
[運(yùn)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(yīng)用B的用戶表異步-同步數(shù)據(jù) |
[導(dǎo)步執(zhí)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(shù)，從而進(jìn)行下一步操作
希望本文所述對大家PHP程序設(shè)計(jì)有所幫助。
