Should I upgrade PHP to 5.4

Are all of you site's compatible with php 5.4 and not using any of the deprecated functions that no longer exist in 5.4 but do exist in 5.3?

This is where it would be nice if Easy Apache allowed concurrent 5.3 and 5.4 installs that were user selectable via cPanel like you could do with php 4 and php 5. It would save a lot of upgrade grief for individual client sites.

 

Most of the time upgrade is better than stay on a version.

 

What would even be nicer is if there was a function that could search for depreciated functions in the users home folder, that way there is a definitive answer as to if your clients sites are compatible.

 

Here's a guide that may be of help.

We upgraded one server to 5.4 and everything is ok.

Thanks for this notice.
I'll use that for any accounts that end up broken due to the switch, since it pushes the responsibility onto the script writers, and not the host running a secure server.

Remember that there are still a lot of people running old scripts of Wordpress and Joomla and other programs. Most don't upgrade.
I had to shut down the Joomla 1.0 sites on my server, and I am pushing the Joomla 1.5 sites to upgrade.

I actually can't believe how many Wordpress sites don't upgrade, when it is a simple click of a button.

 

If you use suhosin you can't upgrade to php 5.4 yet https://forums.cpanel.net/f185/suhosin-not-suhosin-php-5-4-question-310662.html

 

I upgraded to apache 2.4 and/or php 5.4 and smf is totally messed up. The text is gone for the messages and the subjects but the user titles are still showing up for the registered users.
