Php Guys,

Why does this cURL show complete blank page ?

<?php
 
/*
ERROR HANDLING
*/
declare(strict_types=1);
ini_set('display_errors', '1');
ini_set('display_startup_errors', '1');
error_reporting(E_ALL);
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
 
    function curl_download($Url){
  // is cURL installed yet?
  if (!function_exists('curl_init')){
    die('Sorry cURL is not installed!');
  }
  
  $Url = "http://findnerd.com";
 
  // OK cool - then let's create a new cURL resource handle
  $ch = curl_init();
 
  // Now set some options (most are optional)
 
  // Set URL to download
  curl_setopt($ch, CURLOPT_URL, $Url);
 
  // User agent
  curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");
 
  // Include header in result? (0 = yes, 1 = no)
  curl_setopt($ch, CURLOPT_HEADER, 0);
 
  // Should cURL return or print out the data? (true = retu rn, false = print)
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
 
  // Timeout in seconds
  curl_setopt($ch, CURLOPT_TIMEOUT, 10);
 
  // Download the given URL, and return output
  $output = curl_exec($ch);
 
  // Close the cURL resource, and free system resources
  curl_close($ch);
 
  return $output;
}
 
?>
