$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;

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