Dear Lawrence,

try to modify your function from

function dummy($param1 = '', $param2 = '', $param3 = '', $param4 =
'') {
if ($param1) echo $param1;
if ($param2) echo $param2;
if ($param3) echo $param3;
if ($param4) echo $param4;
}

to

function dummy(&$params) {
if (isset($params['first'])) echo $params['first'];
if (isset($params['second'])) echo $params['second'];
if (isset($params['third'])) echo $params['third'];
if (isset($params['forth'])) echo $params['forth'];
}


This way you can use the function e.g. with the fourth parameter only
when you call

dummy(array('forth' => 'testvalue'));


Good luck
Martin
