Hi,

Doing code cleanup; something that seemed so simple is giving me lots of
trouble for whatever reason.

Win 7, XAMPP, PHP 5.3, online forms:

In my cleanup efforts I've been trying to concatenate statements for
things like the following:

IF(strlen(var1) == 0) OR strlen(var2) == 0) OR strlen(var3) ==0))
{
code; notify user of errors that must be corrected.
}

I know OR is || and AND is &&, and have tried every combination of code
I can think of but I consistently get syntax errors and it never works.
Doing each var independently works fine; e.g. if(strlen($var) == 0)
{...}, works as expected, first time every time.

It's when I start to try to use AND or OR that I get in trouble; I
continually get syntax errors, suggesting I don't know what I'm doing,
which I guess is obvious.
At one time I had a downloaded code page explaining precisely how
to OR them together, but darned if I can refind it on my hard drive OR
online either! I just cannot locate the proper way to OR vars together.

Either a code example or URL to such a feature would be great! I am just
not finding anything on Google or otherwise to demo how it works!

Thanks in Advance,

Twayne`
