Check out the manual section on default parameters...
But the basics are:
function top($image = "null") {
if ($image)
...
else
...
}
Or maybe:
That will set image to be null, so that you can call top either as:
top();
or
top($someimage);

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
