方法一:

复制代码 代码如下:


$url="http://www.baidu.com"; 
file_get_contents($url); 



方法二:

复制代码 代码如下:


// CURL 方法 
$url="http://www.baidu.com"; 
$ch = curl_init(  ); 
curl_setopt( $ch,CURLOPT_URL,$url ); 
curl_setopt( $ch,CURLOPT_HEADER,0 ); 
curl_setopt( $ch,CURLOPT_RETURNTRANSFER,1 ); 
$ret= curl_exec( $ch ); 
curl_close( $ch ); 
echo $ret; 

方法三:

复制代码 代码如下:


$url="http://www.baidu.com"; 
$fp=fopen($url,"r"); 
$response = ''; 
while($row = fgets($fp)) { 
$response.= trim($row)."\n"; 
}



注意:如果ping的通但是无法调用远程url,试试wget

复制代码 代码如下:


Resolving www.xxx.com... 114.xxx.xxx.xxx
Connecting to www.xxx.com|114.xxx.xxx.xxx|:80... connected.
HTTP request sent, awaiting response... 403 Forbidden
10:58:22 ERROR 403: Forbidden.



这样就不可以!
