Using PHP 5.2.17 in Acquia Dev Desktop 2 I'm using Acquia Dev Desktop 2 with Drupal 7. On PHP version selection menu, I only see "5.3.29", "5.4.33", "5.5.17".

Is it possible to switch PHP version to PHP 5.2.17 since most of my hosting provider based on PHP 5.2.17.

Or would you recommend anything other than Acquia Dev Desktop 2?

Thank you.
They dropped PHP 5.2 support with DevDesktop 2. It has hit EOL so you really shouldn't be developing against it. 

That said, if you really want to do this, you can find old versions of DevDesktop that used PHP 5.2. I would guess you might hit problems if your end goal is to deploy to AcquiaCloud.
