具体如下:
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
