Make interval for PROGRESSFUNCTION in PHP CURL?

Question

With below code

    curl_setopt($ch, CURLOPT_NOPROGRESS, 0);
    curl_setopt($ch, CURLOPT_PROGRESSFUNCTION, 'progress_upload');

progress_upload function will be triggered many times in a second but how can we set an interval to decrease it?

Answer 1

You can also use a tiny trick in your body function like below

function progress_upload()
{
    
    //contain time of next run
    static $next ;

    $INTERVAL = 5; // unit is second

    $now = time();

    if ( $now > $next ){

      //function body here
      //
      //
      //

      $next = $now + $INTERVAL;

    }

}
