PHP语言实现脚本异步执行

来源：互联网发布：网页美工和前端工作编辑：程序博客网时间：2024/06/10 05:07

php语言得用fsockopen()函数,实现脚本异步运行,代码如下

//异步请求函数(用debug参数若为true则为用为调试,开启调试可以看到异步的执行情况,但是失去异步的效果)

main.php

<?phpfunction request_by_fsockopen($url,$post_data=array(),$debug=false){    $url_array = parse_url($url);    $hostname = $url_array['host'];    $port = isset($url_array['port'])? $url_array['port'] : 80;    @$requestPath = $url_array['path'] ."?". $url_array['query'];    $fp = fsockopen($hostname, $port, $errno, $errstr, 10);    if (!$fp) {        echo "$errstr ($errno)";        return false;    }    $method = "GET";    if(!empty($post_data)){        $method = "POST";    }    $header = "$method $requestPath HTTP/1.1\r\n";    $header.="Host: $hostname\r\n";    if(!empty($post_data)){        $_post = strval(NULL);        foreach($post_data as $k => $v){        $_post[]= $k."=".urlencode($v);//必须做url转码以防模拟post提交的数据中有&符而导致post参数键值对紊乱        }        $_post = implode('&', $_post);        $header .= "Content-Type: application/x-www-form-urlencoded\r\n";//POST数据        $header .= "Content-Length: ". strlen($_post) ."\r\n";//POST数据的长度        $header.="Connection: Close\r\n\r\n";//长连接关闭        $header .= $_post; //传递POST数据    }else{        $header.="Connection: Close\r\n\r\n";//长连接关闭    }    fwrite($fp, $header);    //-----------------调试代码区间-----------------    //注如果开启下面的注释,异步将不生效可是方便调试    if($debug){    $html = '';    while (!feof($fp)) {    $html.=fgets($fp);    }    echo $html;    }    //-----------------调试代码区间-----------------    fclose($fp);}$data=array('name'=>'guoyu','pwd'=>'123456');$url='http://localhost/test/other.php';request_by_fsockopen($url,$data,true);//

other.php

<?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;?>

使用实例:
[运行的main.php主脚本文件]
$data=array('name'=>'guoyu','pwd'=>'123456');
$url='http://localhost/test/other.php';
request_by_fsockopen($url,$data,true);//把应用B的用户表异步-同步数据

[导步执行文件other.php]
在other.php中便可以用$_POST接收main.php提交过来的参数，从而进行下一步操作
