Testing against various PHP versions

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.

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.

I already have a test suite and would like to run it against as many versions of PHP a开发者_C百科s possible.

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