hi all!!
i'm writing functions like -
-------
function top () {
echo "blah blah blah";}
-------
what i want to do is make it so that i can do -
-------
function top($image) {
echo "blah blah $image blah"; }
-------
but also make the $image parameter in the top() as optional. so if
its not there, then tell php not to worry about it.
any ideas??
thanks!
sunny
