One thing of important note would be that getopt() actually respects the '--' option to end an option list.  Thus given the code:

test.php:
<?php
    $options = getopt("m:g:h:");
    if (!is_array($options) ) {
        print "There was a problem reading in the options.\n\n";
        exit(1);
    }
    $errors = array();
    print_r($options);
?> 

And running:

# ./test.php ./run_vfs  -h test1 -g test2 -m test3 -- this is a test -m green

Will return: 

Array
(
    [h] => test1
    [g] => test2
    [m] => test3
)

Whereas running:
# /test.php ./run_vfs  -h test1 -g test2 -m test3 this is a test -m green

Will return:

Array
(
    [h] => test1
    [g] => test2
    [m] => Array
        (
            [0] => test3
            [1] => green
        )

)
