ID: 29082 User updated by: markem at ev1 dot net Reported By: markem at ev1 dot net Status: Bogus Bug Type: Scripting Engine problem Operating System: Windows98se PHP Version: 4CVS-2004-07-10 (stable) New Comment:
Ok. I went back to the O'Reilly book and re-read the section on "Missing Parameters" on page 69 of the March 2002, First Edition. I see where the warning message is stated to occur and I know about the suppression of the warning messages. I can live with that. This leaves me with question #2. That of why the null parameters are not being interpreted as null parameters and instead PHP dies when it attempts to interpret them. I feel that this is a valid problem as, in some (but not all) other languages the empty set on call lines simply becomes a null value. Further, PHP's dying in this case negates the "Missing Parameters" section on page 69. I will though, go talk with people on the help boards and see what they say about this. Thanks for you time and sorry about #1. Later!

If not having to pass arguments to a function (variable call arguments) is normal, then why does PHP generate a warning about missing arguments? 2. If variable call arguments are possible - why can you not call the function in this manner: $theLine .= tb(,,"#ffffff"); ??????? PHP should treat the empty ",," as two nulls. Instead, an error is generated by PHP and PHP dies. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29082&edit=1
