Following code returns the curl output as a string.

<?php
       
// create curl resource
       
$ch = curl_init();

       
// set url
       
curl_setopt($ch, CURLOPT_URL, "example.com");

       
//return the transfer as a string
       
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

       
// $output contains the output string
       
$output = curl_exec($ch);

       
// close curl resource to free up system resources
       
curl_close($ch);     
?>

true;
}

/*

    {
      if( !
curl_setopt($ch, CURLOPT_URL, $url) )
      {
       
fclose($fp); // to match fopen()
