Upgrade PHP from version 5.2 to 5.3

I have 15 sites implemented with some functions that are deprecated in PHP 5.3. My hosting provider is offering me a new server, but it has php 5.3 installed on it. I need to upgrade all of my code to 5.3, because the server move is imminent, so I was wondering what's the best way to identify/correct the files that have deprecated functions.

I tried with PHP_Codesniffer, and it's giving me the list of files and the exact functions that won't work in PHP5.3, but I still need to edit the files one by one. Is there another extension/program that could help me with this? (just trying to avoid all of the tedious work of going into all of the files one by one)

Thanks

Answer 1

Download and install Sublime Text 2, Notepad2, Notepad++, etc. They all have search & replace in a specified directory. You'll have to do a search & replace for each thing you want to change, but it's faster that doing it one file at a time.

Check out this document about the changes between 5.2 and 5.3: http://php.net/manual/en/migration53.php
