This is <span class=""caps"">PHP</span> 5+ only and supports MySQL 5+ and PostgreSQL 8+. Although I do realise that earlier versions of these packages are still quite widely used out there, this project probably won&#8217;t hit the big 1.0 for another year or two, by which time, the hosting world will have probably moved on a lot. Supporting older versions of <span class=""caps"">PHP </span>and the database engines will cost development time and push back the project release date even later, by which time <span class=""caps"">PHP</span> 4 support will be even less relevant.</p>  <p>So although <span class=""caps"">PHP</span> 4 may still be alive right now, it&#8217;s counting down the days to his retirement when it can hand over the family business to his son <span class=""caps"">PHP</span> 5. He&#8217;s heard the happy news that his dranddaughter <span class=""caps"">PHP</span> 6 is planning on following in their footsteps too as soon as she graduates. Because of <span class=""caps"">PHP</span> 4&#8217;s impending retirements, he&#8217;s not taking on&#8230;</p>"
