PHP CURL發送POST請求

<?php  
  $ch = curl_init();  
  $timeout = 5;  
  curl_setopt ($ch, CURLOPT_URL, 'http://www.domain.com/');  
  curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);  
  curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); 
  curl_setopt($ch, CURLOPT_POST, 1 );//設置post請求
  curl_setopt($ch, CURLOPT_HEADER, 0 ) ;
  curl_setopt($ch,CURLOPT_POSTFIELDS, "param=".$param);//param爲請求的參數
  $file_contents = curl_exec($ch);  
  curl_close($ch);  
  echo $file_contents;
?>

public function remoteByRolling($urls, $param) {
		
        if (! is_array ( $urls ) || count ( $urls ) == 0)
