I have a bunch of predefined constants starting with GPERM_ in addition to some other defined constants. How can I take the values of every constant that starts with GPERM_ and make it into a string that looks like value1,value2...valuen?

NM, figured it out (I imploded the array later on):

PHP Code:

echo 'Creating list of user permissions...';
    $constants = get_defined_constants();
    $perms = array();
    $current = each($constants);
    define('PERM_PREFIX', 'GPERM_');
    while ($current != false)
    {
        if (substr($current['key'], 0, strlen(PERM_PREFIX)) == PERM_PREFIX)
        {
            array_push($perms, $current['value']);
        }
        $current = each($constants);
    }
    echo 'Done<br>';
