PHP异步调用socket简单实例

文章利用了socket来实现异步调用,有需要学习socket的朋友可以参考一下本文章以及参考资料,代码如下:

<?php 
    $host = "www.phprm.com"; 
    $path = "/Report.php?ReportID=1"; 
    $cookie = Session_id(); 
    
    $fp = fsockopen($host, 80, $errno, $errstr, 30); 
    if (!$fp) { 
       print "$errstr ($errno)<br />n"; 
       exit; 
    } 
    $out = "GET ".$path." HTTP/1.1rn"; 
    $out .= "Host: ".$host."rn"; 
    $out .= "Connection: Closern"; 
    $out .= "Cookie: ".$cookie."rnrn"; 
    fwrite($fp, $out);  //将请求写入socket 
    //也可以选择获取server端的响应 
    /*while (!feof($fp)) { 
        echo fgets($fp, 128); 
    }*/ 
    //如果不等待server端响应直接关闭socket即可 
    fclose($fp);
