Is there a tool to manage multiple installations of PHP on one machine (e.g. to support different versions)?
php
Solution
Here's one: http://www.navicopa.com - it allows you to switch between different versions of php in one click (just install them into different directories)
And here's a free one: https://github.com/c9s/phpbrew
Also - you might like this solution as an alternative, if you don't want to use side software: https://stackoverflow.com/a/5299385/1337343
Also missed that you use linux environment, so you would really like this: https://github.com/tobiasgies/php-switch
Install all php versions you need and switch between them using this tiny bash script.
Problem
perlbrew is a tool to manage multiple installations of Perl on your system, making it easy to, say, quickly run a suite of test scripts against many different versions of Perl. Is there anything like that for PHP? For now when I want to change the version of PHP that my system uses, I'll go into the build directory for my desired version and run `make install`.
