[Resolved] strlen() usage

[ghjr]

I have a for loop that runs a strlen():

for ($this_cont=0; $this_cont<$global_not; $this_cont++) {
echo strlen("not" . $this_cont);
}

What I want to run the strlen() on are variables called $not0, not1, $not2 and so on. Trouble is, the function just outputs 4 for each variable, since it doesn't really consider it a variable (just a string starting with "not" and ending with a number).

Any way to make strlen() look for the variable $not1 and not "not1"?

Cheers!!

It's not strlen, it's your variable usage. You need to use variable variables.

# this
echo strlen("not" . $this_cont); 

# should be
echo strlen(${"not".$this_cont});

Thanks Lord, that did it. I didn't know how to use variable variables.

Thanks again. 😃
