RVM equivalent for PHP?

I can't seem to find a way to switch versions of PHP quickly. Is there something equivalent to ruby version manager for php? I need to switch between 5.3 and 5.2 on OS X.

For PHP alternatives to RVM and rbenv, you have phpbrew, phpenv and php-version. Please be aware that I am the author of php-version so of course I prefer it as I wrote it to scratch my own itch (I wanted something minimal with command completion); however, phpenv is quite good as well. You would do well to use either.

On OS X, you can install a PHP version manager using Homebrew.

First, add the PHP formulae for homebrew:

% brew tap homebrew/homebrew-php

Then, using the formulae installed from homebrew-php you can install either with:

% brew install php-version

or

% brew install phpenv

The php-version README.md lists a few more alternatives so you might want to have a look.

BTW, I would consider php-version to be more aligned with chruby in that it tries to do one thing well.

I think phpfarm is most close php alternative of rvm, it also installing pyrus which is like ruby gems for php world.
