本文为大家整理总结了PHP打开获取远程URL地址内容的几种方法：file_get_content,curl,fopen,fsockopen等，感兴趣的同学参考下。 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(); ?> 示例代码2: 用fopen打开url, 以get方式获取内容 <? $fp = fopen($url, 'r'); printarr(stream_get_meta_data($fp)); printhr(); while(!feof($fp)) { $result .= fgets($fp, 1024); }

本文为大家整理总结了PHP打开获取远程URL地址内容的几种方法：file_get_content,curl,fopen,fsockopen等，感兴趣的同学参考下。


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();
?>


示例代码2: 用fopen打开url, 以get方式获取内容

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


示例代码3：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;
?>


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

 


<?
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;
}

?>


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

 


<?
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();
?>


示例代码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

 


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


关于curl库：
curl官方网站http://curl.haxx.se/
curl 是使用URL语法的传送文件工具，支持FTP、FTPS、HTTP HTPPS SCP SFTP TFTP TELNET DICT FILE和LDAP。curl 支持SSL证书、HTTP POST、HTTP PUT 、FTP 上传，kerberos、基于HTT格式的上传、代理、cookie、用户＋口令证明、文件传送恢复、http代理通道和大量其他有用的技巧

 

<?
function printarr(array $arr)
{
echo "<br> Row field count: ".count($arr)."<br>";
foreach($arr as $key=>$value)
{
echo "$key=$value <br>";
}
}
?>


7.
有些主机服务商把php的allow_url_fopen选项是关闭了，就是没法直接使用file_get_contents来获取远程web页面的内容。那就是可以使用另外一个函数curl。
下面是file_get_contents和curl两个函数同样功能的不同写法
file_get_contents函数的使用示例:

 


< ?php
$file_contents = file_get_contents('http://www.ccvita.com/');
echo $file_contents;
?>


换成curl函数的使用示例:

 

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


利用function_exists函数来判断php是否支持一个函数可以轻松写出下面函数

 


< ?php
function vita_get_url_content($url) {
if(function_exists('file_get_contents')) {
$file_contents = file_get_contents($url);
} else {
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
}
return $file_contents;
}
?>


其实上面的这个函数还有待商榷，如果你的主机服务商把file_get_contents和curl都关闭了，上面的函数就会出现错误。
