PHP語言實現腳本異步執行

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)

main.php

    <?php

    function 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);//必須做url轉碼以防模擬post提交的數據中有&符而導致post參數鍵值對紊亂

            }

            $_post = implode('&', $_post);

            $header .= "Content-Type: application/x-www-form-urlencoded\r\n";//POST數據

            $header .= "Content-Length: ". strlen($_post) ."\r\n";//POST數據的長度

            $header.="Connection: Close\r\n\r\n";//長連接關閉

            $header .= $_post; //傳遞POST數據

        }else{

            $header.="Connection: Close\r\n\r\n";//長連接關閉

        }

        fwrite($fp, $header);

        //-----------------調試代碼區間-----------------

        //注如果開啟下面的注釋,異步將不生效可是方便調試

        if($debug){

        $html = '';

        while (!feof($fp)) {

        $html.=fgets($fp);

        }

        echo $html;

        }

        //-----------------調試代碼區間-----------------

        fclose($fp);

    }


$data=array('name'=>'guoyu','pwd'=>'123456');  
$url='http://localhost/test/other.php';  
request_by_fsockopen($url,$data,true);//  </pre> 



 other.php 

    <?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
