Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in

Since PHP 5.5 has removed support for mysql extension in favor of mysqli.  It's highly recommended to upgrade to phpGrid 6.0 to address mysql extension deprecation. 

If you have phpGrid version less than version number 6.0, add the following to the top of your page to surpress the warning. However, it's a not recommended practice for production.
