[Resolved] Extracting Numbers from a String

[jawa]

I've building an app relating to a trading card game. I've got the casting cost of each card input into a string, i.e. 2BB

I want to calculate the total cost of the card. In this case, it would be 4. 2 + B + B.

The problem I'm having is I'm parsing out the string character by character, and checking it's type. When I pull the 2 out, it treats it like a string.

I'm using:

$length = strlen($Casting_Cost);
for ($i=0;$i<$length;$i++) {
	$char = substr("$Casting_Cost", $i, 1);
	if (is_string($char)) {
		echo ("char is a string...");
	}
	else if (is_int($char)) {
		echo ("char is a int...");
	}
}

It's never hitting the is_int part of the if statememt.

How can I get the 2 to be treated like an integer?

Thanks,

is_int is strict, so it would never equate to true. Use is_numeric instead.

Worked like a charm. Thanks a bunch!
