PHP is probably the best language to talk with web. But it isn’t good when you need to work with command line. When I started work with SugarCRM I’ve discovered that about 40% of tasks like synchronization with related systems, massive updates etc should be done in the command line and not via HTTP. There are my suggestions based on my experience (it is not so wide of course ).
To run PHP script from command line you just need to run following:

To have possibility to run PHP script without typing PHP let’s add path to the interpretaror in the begging of the script:

#!/usr/bin/php
< ?php
    echo "Hello World!";
?>

Now to run PHP script we need to type just its name:

Note : Be sure the script is execvutable (chmod +x example.php)
Well, let’s suppose we need to send some argument to our script. PHP has a variable $argc which contains a nuber of input arguments and array $argv which contains input arguments essentially. Notice that $argv[0] is the script name (it’s terribly and not obviously). Therefore we should use index started from 1 to get out arguments:

If we run our script like that

we see following result

One thing you should know to work with command line. You have to compile PHP with CLI support:

That option is set in true by default. But who knows probably your system administrator disabled it. If CLI support switched off and you don’t want to recompile PHP you can access to the command line parameters via global array $_SERVER:

Maybe, it’s not perfect but it’s working!
One suggestion at the end: be sure that it is defined enough memory and run time in your PHP.ini:
