Question

Is it possible to loop based on a specific variable name for a $_REQUEST for example:

if (!$POST)
{
do something
}

else {

if ($_REQUEST['name1'])
{
do something
}
elseif ($_REQUEST['name2'])
{
do something
}

}

Really you can get as complex as you want:

foreach($_REQUEST as $key => $val)
{
    switch($key)
    {
        case 'name1':
            if(is_array($val))
            {
                foreach($val as $v)
                {
                     // do something for each element in the $_REQUEST['name1'] array
                }
            }
            else
            {
                // do something for $_REQUEST['name1'] which is not an array
            }
            break;

        case 'name2':
            if(is_array($val))
            {
                foreach($val as $v)
                {
                     // do something for each element in the $_REQUEST['name2'] array
                }
            }
            else
            {
                // do something for $_REQUEST['name2'] which is not an array
            }
            break;
    }
}
