there are a few things to help and make things tidy

edit your php.ini file, find register_argc_argv and make sure it is set to: 

register_argc_argv = On

create your fraction.php script for example: 

#!/usr/bin/php -q
<?php
echo "arg1: ".$argv[1]."\n";
echo "arg2: ".$argv[2]."\n";


NOTE: #! line is a smart bit, so you don't need to use php for the command line when running the script./usr/bin/php may be different on your computer:

# whereis php

chmod script, so you can run it directly from the command line: 

# chmod 755 fraction.php

Finally, run the script:
. /fraction.php "1 1/7" "2 2/7"
