How can I make PHP progressbar and pecl uploadprogress work together on a CentOS 6.6 with cPanel system?

To make PHP progressbar and pecl uploadprogress work together on a CentOS 6.6 with cPanel system, you will need to install the pecl uploadprogress extension and configure your PHP settings to enable it. You can then use the uploadprogress functions in your PHP code to display progress bars for file uploads.

// Install pecl uploadprogress extension
pecl install uploadprogress

// Enable the extension in your php.ini file
extension=uploadprogress.so

// Use the uploadprogress functions in your PHP code
$progress = uploadprogress_get_info($_POST['UPLOAD_IDENTIFIER']);
echo $progress['bytes_uploaded'] . ' bytes uploaded out of ' . $progress['bytes_total'];
