Hello If I defined a function with 4 parameters but only pass 3 I get an error. Is there anyway around this? I want to be able to set the missing parameter to a default value if it is not passed which works ok but How do I get rid of the error message? Thanks Giles Roadnight http://giles.roadnight.name

If you want an argument to be optional and still be able to check whether or not it's been set, you can use NULL as the default value: function foobar ($a, $b, $c = null) {

    if (isset($c)) {
        echo 'The third argument was set';
    }
