[php] How to downgrade php from 5.5 to 5.3

I did this in my local environment. Wasn't difficult but obviously it was done in "unsupported" way.

To do the downgrade you need just to download php 5.3 from http://php.net/releases/ (zip archive), than go to xampp folder and copy subfolder "php" to e.g. php5.5 (just for backup). Than remove content of the folder php and unzip content of zip archive downloaded from php.net. The next step is to adjust configuration (php.ini) - you can refer to your backed-up version from php 5.5. After that just run xampp control utility - everything should work (at least worked in my local environment). I didn't found any problem with such installation, although I didn't tested this too intensively.
