I'm trying to make a PHP script that will take a potentially infinite number of URLs from the command line as arguments. I also need to pass an argument that only has a single numeric value possible (to specify timeout), e.g.:

./urltest.php 60 url1.com url2.com url3.com

I'm not exactly sure how to specify argv[1] to be a single numeric variable while at the same time the rest of the arguments (i.e. the list of urls) go into an array. Maybe something like:

$timeout = $argv[1];
$args = func_get_args();    

function numfilter($num) {
    return !is_numeric($num);
}

$urls = array_filters($args, 'numfilter');

?

Thanks in advance!
