PHP - Execute code from terminal, ubuntu server

Question

I know that you can run php files from terminal with linux running PHP... I.e. "php script.php" ... But is there any program that allows you to directly input php into the terminal (through any intermediary program) and output the results? I.e. In terminal, testing php globals like getinfo(), etc..? Any help would be great, I'd like to test functions and commands through a sort of run-time terminal. Thanks!

Answer 1

php -r 'phpinfo();'

worked for me on OSX.

Answer 2

php -a (as of PHP 5.1) should do what you want.

You might like a program called PHP Shell Terminal: http://sourceforge.net/projects/phpterm/
