Check out the official guide about Migrating from PHP 5.2.x to PHP 5.3.x
most existing PHP 5 code should work without changes, but make sure error-reporting is enabled to get some idea of what is going wrong .
I was asked to help getting a website that was running with 5.2 php code, to work on a 5.3 php server. The site is big, and I can't see the errors that would appear normally when a site isn't working.
I've tried to use the Search and replace function that Dream Weaver has, and simply use it all over the website. But the problem is that I only want to replace functions in PHP documents, and not in js files. When i use Search and replace, in Dreamweaver, it overwrites the js files aswell, and that would cause more errors. Because there's A LOT of files that i have to go through, it would take me a lot of time if i had to go through it manually.
I figured this must be a problem that a lot of firms experiance, so there must be ways to handle this without it being a bigger hassle.
Anybody out there who could help me out ? Any help is much appreciated!
