On my production server the highest version of php i can run is 5.3.13.
Looking at the preferences panel in MAMP(v2.1.3) i have two options for the php either 5.2.17 or 5.4.10.
Is there an install or a plugin that i can add to allow me to use additional releases of php, so that i can mimic the environment i have setup on the production server ?
