PHP implements a method of asynchronously writing content (pictures or content) on a remote link to a local _php tips

The example in this article describes how the PHP implementation asynchronously writes the content (picture or content) on a remote link to the local method. Share to everyone for your reference, specific as follows:

/** * Writes the content (picture or content) on the remote link asynchronously to the local * @param unknown $URL * Remote address * @param unknown $s Avename * file name saved on the server * @param unknown $path * Save path * @return Boolean/function Put_file_from_url_content ($url, $saveName = ' tmp.png ', $path = './uploads/tmp/')
  {//Set run time to unrestricted set_time_limit (0);
  $url = Trim ($url);
  $curl = Curl_init ();
  Set the URL you need to crawl curl_setopt ($curl, Curlopt_url, $url);
  Set HEADER curl_setopt ($curl, Curlopt_header, 0);
  Sets the curl parameter to require that the results be saved to the string or to the screen.
  curl_setopt ($curl, Curlopt_returntransfer, 1);
  Run Curl, request Web page $file = curl_exec ($curl);
  Closes the URL request curl_close ($curl); Writes a file to the obtained data $filename = $path.
  $saveName;
  $write = @fopen ($filename, "w");
  if ($write = = False) {return false;
  } if (Fwrite ($write, $file) = = False) {return false;
  } if (fclose ($write) = = False) {return false;
return $filename; }
