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
<?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
<?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
