方法1: 用file_get_contents 以get方式獲取內(nèi)容：

<?php$url='http://www.jb51.NET/';$html = file_get_contents($url);echo $html;?>

方法2: 用fopen打開(kāi)url, 以get方式獲取內(nèi)容：

<?php$fp = fopen($url, ‘r');stream_get_meta_data($fp);while(!feof($fp)) {$result .= fgets($fp, 1024);}echo “url body: $result”;fclose($fp);?>

方法3：用file_get_contents函數(shù),以post方式獲取url

<?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函數(shù)打開(kāi)url，以get方式獲取完整的數(shù)據(jù)，包括header和body,fsockopen需要 php.ini 中 allow_url_fopen 選項(xiàng)開(kāi)啟

<?phpfunction get_url ($url,$cookie=false){$url = parse_url($url);$query = $url[path].”?”.$url[query];echo “Query:”.$query;$fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30);if (!$fp) {return false;} else {$request = “GET $query HTTP/1.1rn”;$request .= “Host: $url[host]rn”;$request .= “Connection: Closern”;if($cookie) $request.=”Cookie:  $cookien”;$request.=”rn”;fwrite($fp,$request);while(!@feof($fp)) {$result .= @fgets($fp, 1024);}fclose($fp);return $result;}}//獲取url的html部分，去掉headerfunction GetUrlHTML($url,$cookie=false){$rowdata = get_url($url,$cookie);if($rowdata){$body= stristr($rowdata,”rnrn”);$body=substr($body,4,strlen($body));return $body;}return false;}?>

方法5：用fsockopen函數(shù)打開(kāi)url，以POST方式獲取完整的數(shù)據(jù)，包括header和body

<?phpfunction HTTP_Post($URL,$data,$cookie, $referrer=”"){// parsing the given URL$URL_Info=parse_url($URL);// Building referrerif($referrer==”") // if not given use this script as referrer$referrer=”111″;// making string from $dataforeach($data as $key=>$value)$values[]=”$key=”.urlencode($value);$data_string=implode(“&”,$values);// Find out which port is needed
