Testing against various PHP versions
<p>I have a PHP app that I would like to test against various PHP versions.  I don't need to configure it with Apache or mysql, a simple php command line binary would do.  I would however need cURL with SSL support compiled in.</p>

<p>The reason I ask as I tried compiling my own and ran into all sorts of issues with newer versions of curl don't work with older versions of PHP etc.</p>

<p>I already have a test suite and would like to run it against as many versions of PHP as possible.</p>

<p>Is there a good way to do this short of manually compiling a ton of php binaries?</p>
