We are currently using PHP 5.3.8 version on our WP site running 3.3.2. I need to upgrade my PHP version to 5.3.9 or newer without PHPMyAdmin and CPanel, and the web site is hosted locally. Our sys admin guys don't knw anything about PHP upgrades on the web server. Is there a way I can upgrade the version? (We can't install PHPMyAdmin and CPanel) due to security reasons. Any help would be great. Thanks.
