keeping variables in loops

jpfour23

Hey Everyone,

Quickie for you.... But I'm lost. How do I keep a variable or use it elsewhere when its inside a 'for' loop.

Example:

for ($i = 0; $i < $times; $i++) {
	$list = "<li>$var[$i]";
	echo $list;
}

echo $list;  ???

I am wanting to use $list outside of the for loop... like in an SQL query:

 $sql = "UPDATE blah SET listing='$list', etc";

THANKS!

Nevermind... I figured out that for

for ($i = 0; $i < $times; $i++) {
$list = "<li>$var[$i]";
echo $list;
}

I needed to make $list .= and not =

Thanks anyhow!!

Hi - could you explain that .= thing to me? I have been trying to figure out what it does but haven't had any luck so far.

Thanks a lot.
