Body: <p>What PHP version would you recommend for running CiviCRM version 4.6.8? </p>
  
  <p>I was using an old version of PHP (4.3.3), but that is no longer sufficient to run CiviCRM and 5.4+ is recommended in the documentation. Would it be wise to upgrade to the latest version 5.6.13 or might I be safer with something like 5.5.29? </p>

  What PHP version would you recommend for running CiviCRM version 4.6.8?
  
  I was using an old version of PHP (4.3.3), but that is no longer sufficient to run CiviCRM and 5.4+ is recommended in the documentation. Would it be wise to upgrade to the latest version 5.6.13 or might I be safer with something like 5.5.29?

  The safest bet is probably 5.5. 5.6 ought to work but hasn't been tested as thoroughly. As a core CiviCRM developer I currently use 5.5.9 in my test environment.
  
  You should also look at which version is recommended for your CMS, often that is more of a limiting factor.
