在一台机器上设置两个php版本[关闭]

I was asked in an interview.

How can we set up two different php version ex:php v 5.0 and php v 5.3 in a single machine?

Is it possible to do it with apache?

Thanks

1. Install the 2 php versions to unique paths.

2. Install 2 apache's each running on a different port

3. Setup each apache conf to use a different php version
