<?php$data = array (‘foo' => ‘bar');$data = http_build_query($data);$opts = array (‘http' => array (‘method' => ‘POST',‘header'=> “Content-type: application/x-www-form-urlencodedrn” .“Content-Length: ” . strlen($data) . “rn”,‘content' => $data));$context = stream_context_create($opts);$html = file_get_contents(‘http://localhost/e/admin/test.html', false, $context);echo $html;?> |
方法4：用fsockopen函数打开url，以get方式获取完整的数据，包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 选项开启

方法6:使用curl库，使用curl库之前，可能需要查看一下php.ini是否已经打开了curl扩展
