php.net, but

It is a ternary IF statement...verbose

dian;

HW what does (boolean)$bool mean?
It's casting the value ($bool) to a boolean (i.e. TRUE or FALSE).

That's a boolean casting; used for forcing a variable to become
boolean... Hope it helps...

It's a shortened version of the if...else construct. As in...
condition ? this_if_true : this_if_false

I'm stumped by the
exact meaning in the following function of what the question mark's (?)

That's the ternary comparison operator. See
http://www.php.net/manual/en/language.operators.comparison.php,
The ? in this senario is called the ternary operator
basically shorthand for an if/else statement e.g
$theValue = ($theValue != ) ? ' . $theValue . ' :NULL;
is the equivalent of
if($theValue != ) {
$theValue =$theValue ;
}
else{
$theValue =NULL;
}

a pointer to the address (mem) of the variable
PHP doesn't have pointers and memory can't be directly accessed this way
like you can in C, or C++ or whatever. The ampersand is for passing values
via reference
Ouupppss!!
You're right !!!

Warning: Cannot use a scalar value as an array
what does that mean?
i have in my code this:
$errorMsg[error] =
As far as I know, you've defined $errorMsg previously
as an variable, not as an array. If you'll not use
anymore the previously defined $errorMsg just unset the
variable using unset($errorMsg) before the
attribution.
I hope this solves your problem, it solved a lot of
similar errors to me!
I am not very sure of what exactly does this this mean but I guess that the
particular module that you are installing requires a cversion of PHP that
has to be greater than 3.0.8.
This is just a guess. I aplogize if it's wrong.
