PHPはurlの関数コードを取得する

 
  
function geturl($url) 
  
{ 
  
$ch = curl_init(); 
  
$timeout = 5; 
  
curl_setopt($ch, CURLOPT_URL, $url); 
  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
  
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); 
  
//                    
  
//curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY); 
  
//curl_setopt($ch, CURLOPT_USERPWD, US_NAME.”:”.US_PWD); 
  
$contents = curl_exec($ch); 
  
curl_close($ch); 
  
$contents = str_replace("document.write('","",$contents); 
  
$contents = str_replace("');","",$contents); 
  
$contents = str_replace("\
","",$contents); 
  
$contents = str_replace("\\","",$contents); 
  
echo $contents; 
  
}
