if you pass a third parameter, then $zip will equal that parameter If you only pass two parameters, then $zip will equal "6666"
eg1. myFunction($var1, $var2); $zip will = 6666 eg2. myFunction($var1, $var2, $var3); $zip will = $var3, no matter what $var3 contains $var3 could be null, "", or "foobar", it doesn't matter, $zip will = $var3 Martin -----Original Message----- From: Shane [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 11, 2002 10:22 AM To: Martin Towell; [EMAIL PROTECTED] Subject: RE: [PHP] Easy Function Question? Martin, so if I write... function myFunction($name, $phone, $zip="6666"){ echo $name.$phone.$zip } and $zip is NOT SET then $zip will = 6666. But if $zip IS SET then $zip will = whatever $zip's current value is, and will NOT be changed to 6666? Please advise.

I have a need to call a function, where all the variables used might not be set. Is there a way to have a variable in a function have a default setting if the variable passed to the function is VOID? EXAMPLE: $name="me"; $phone="5555"; //$zip is VOID function myFunction($name, $phone, $zip){ echo $name.$phone.$zip } can I write...? function myFunction($name, $phone, $zip="6666"){ echo $name.$phone.$zip } and then $zip will have a value of 6666 if $zip is VOID for some reason...? I thought it was something like this, but I keep batting ZERO and there is no mention of this problem in the places I looked in the docs. Can anyone throw me a bone?
