Robin, I think you hit it exactly on the head with the quote issue.
Steve, use regular single or double quotes, not any kind of fancy
quotes or backticks. It may be the editor you're using: if you use
Microsoft Word or another similar word processor, it may replace the
quotes with something it things is "prettier". If you're using
Windows, use notepad, `edit.com` from the command line, or download
any IDE you'd like - many or which are free and open source, and even
handle PHP specifically.

oh dear, krazee quotes... at least I presume that's what those wierd
characters are.
Look in the manual for isset() (http://www.php.net/isset) and empty()
(http://www.php.net/empty).

[PHP] Not Null?
Greetings,
I have a script that looks for the variable to be NULL and then execute. Is
there a way for the script to look for anything or something in the variable
and then execute?
Ex:
If ($a¹ == ANYTHING¹) {
some action
}else{
some other action
}
Thank you for any help.

Are you referring to the (INT, NOT NULL, PRIMARY) field being in a database?

[PHP] not null
Hi,
When a field is declared as an integer, not null and is the primary,
how would I address it's empty set?
ex: if($value == ???)
{
bla
bla
bla
}
My condition wants there to be nothing in $value.
