PHP-FPM Compiling multiple versions of PHP

Hi,

---

I have a test server running Centminmod 1.2.3-eva2000.08 and I'm wondering how I could go about having multiple versions of PHP installed and usable.

I have a web app that still requires php version 5.3 but would like to test applications on higher versions.

Setting up additional php pools is ok however any tips on compiling php without overriding the 5.3 version that i've configured would be great.

Thanks in advance,

 

Thanks for the fast reply! Virtualbox it is.
