Default parameter

[Mike]

If possible, how do I use a function to create a default parameter
value? The following gives me an "unexpected '(', expecting ')'"
error, which makes sense.

function DisplayInfo($ID , $startdate=date ("Ydm"), $numdays=7) {
...function here...
}

Default arguments have to be constant values, no variables or function
calls. You could use something like this:

function DisplayInfo($ID , $startdate = NULL, $numdays = 7) {
if (is_null($start date)) {
$startdate = date('Ydm');
}
...
}

The default value has to be a constant. It cannot be a variable or a
class member or (as you noticed) a function call.
function DisplayInfo($ID , $startdate=NULL , $numdays=7) {
if (is_null($start date)) $startdate = date('Ydm');
...function here...
}

Thanks for clearing that up. I ended up using '$startdate="bl urgh"'

if ($startdate="bl urg"){
$startdate=date ("Ymd");
}
