using PHP 5.2 when PHP 5.3 is installed

hello
I have installed esayphp with the PHP 5.3 and installed Joomla over it.
I want to install a module (joomfish) which is not working with PHP 5.3 but only with PHP 5.2. I would like to know if it is possible to use PHP 5.2 when the 5.3 is installed without reinstalling easyphp.
thank you
Olivier

That's more simple with php tutorial.

And if you want to save your time use web forms
