How a PHP script can be executed using Command Line?

Answer 1

you can use php -f option to specify the file to be executed

Answer 2

I am assuming that you are using the Linux command line:

One option you have to install php shell (http://www.phpsh.org/ ) and another one what @Shyam has suggested i.e. $ php <filename> (-f is optional)

Answer 3

Just Run the PHP Command Line Interface(CLI) program and provide the PHP script file name as the command line argument.
