How to determine which version of PHP you are using

If you're programming with PHP at some point you will need to know which version you are using.


If you're using OSX you can open Terminal by typing:
cmd + space bar
or just going to Applications -> Utilities and clicking on the Terminal icon.


On the command line in Terminal type:
php -v
The -v flag means version. This will show you which version of PHP you are using. For more options to the php command you can type man php.
