<?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
