php远程打开文件的方法

1、用file_get_contents以get方式获取内容

<?php 
$url='http://www.baidu.com/'; 
$html = file_get_contents($url); 
//print_r($http_response_header); 
ec($html); 
printhr(); 
printarr($http_response_header); 
printhr(); 
?> 

2、用file_get_contents函数,以post方式获取url

<?php 
$data = array ('foo' => 'bar'); 
$data = http_build_query($data); 
$opts = array ( 
'http' => array ( 
'method' => 'POST', 
'header'=> "Content-type: application/x-www-form-urlencoded" . 
"Content-Length: " . strlen($data) . "", 
'content' => $data 
), 
); 
$context = stream_context_create($opts); 
$html = file_get_contents('http://localhost/e/admin/test.html', false, $context); 
echo $html; 
?> 

3、用fopen打开url, 以get方式获取内容

<?php 
$fp = fopen($url, 'r'); 
printarr(stream_get_meta_data($fp)); 
printhr(); 
while(!feof($fp)) { 
$result .= fgets($fp, 1024); 

echo "url body: $result"; 
printhr(); 
fclose($fp); 
?> 

4、用fsockopen函数打开url,以get方式获取完整的数据,包括header和body

<?php 
function get_url ($url,$cookie=false) { 
$url = parse_url($url); 
$query = $url[path]."?".$url[query]; 
ec("Query:".$query); 
$fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30); 
if (!$fp) { 
return false; 
} else { 
$request = "GET $query HTTP/1.1"; 
$request .= "Host: $url[host]"; 
$request .= "Connection: Close"; 
if($cookie) $request.="Cookie: $cookien"; 
$request.=""; 
fwrite($fp,$request); 
while(!@feof($fp)) { 
$result .= @fgets($fp, 1024); 

fclose($fp); 
return $result; 


//获取url的html部分,去掉header 
function GetUrlHTML($url,$cookie=false) { 
$rowdata = get_url($url,$cookie); 
if($rowdata) 

$body= stristr($rowdata,""); 
$body=substr($body,4,strlen($body)); 
return $body; 

return false; 

?> 

5、用fsockopen函数打开url,以POST方式获取完整的数据,包括header和body

<?php 
function HTTP_Post($URL,$data,$cookie, $referrer="") { 
// parsing the given URL 
$URL_Info=parse_url($URL); 
// Building referrer 
if($referrer=="") // if not given use this script as referrer 
$referrer="111"; 
// making string from $data 
foreach($data as $key=>$value) 
$values[]="$key=".urlencode($value); 
$data_string=implode(";",$values); 
// Find out which port is needed - if not given use standard (=80) 
if(!isset($URL_Info["port"])) 
$URL_Info["port"]=80; 
// building POST-request: 
$request.="POST ".$URL_Info["path"]." HTTP/1.1n"; 
$request.="Host: ".$URL_Info["host"]."n"; 
$request.="Referer: $referern"; 
$request.="Content-type: application/x-www-form-urlencodedn"; 
$request.="Content-length: ".strlen($data_string)."n"; 
$request.="Connection: closen"; 
$request.="Cookie: $cookien"; 
$request.="n"; 
$request.=$data_string."n"; 
$fp = fsockopen($URL_Info["host"],$URL_Info["port"]); 
fputs($fp, $request); 
while(!feof($fp)) { 
$result .= fgets($fp, 1024); 

fclose($fp); 
return $result; 

printhr(); 
?> 

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

<?php 
$ch = curl_init(); 
$timeout = 5; 
curl_setopt ($ch, CURLOPT_URL, 'http://www.zhiai1314.net/'); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); 
$file_contents = curl_exec($ch); 
curl_close($ch); 
echo $file_contents; 
?>
