If you want to run/test oneliners in PHP on the command line you can use the -r option.

php -r 'echo "Hello World";' 

Will simply output “Hello World” on the command line

I sometimes use this method to test regexp expressions

php -r 'echo preg_match("/^Test/", "This is a test");'

Here I check if $string starts with the string ‘Test’ (the answer is no).

Using onliners on the command line can sometimes be very handy
