In the following code...
--snip-- <?PHP $name = "bob"; Showmessage("hello $name"); Exit; Function Showmessage($msgvar = null) { echo $msgvar; } ?> --snip--
What is the purpose in the function def of "($msgvar = null)"?? Why not just "function showmessage($msgvar)"??
It's to set a default value if no argument is passed to the function when called like
Showmessage();
In this case $msgvar inside the function will have a null value.
