RegEX look for - (minus sign) in result

xenlab

I'm looking to create a rountine, possibly with RegEX. I want to look at a string, and if it is has a - (minus sign) in it highlight it in red, if not, display it as green.

Is there a function like is_negative() or will i need RegEX to search for it in the string and then do my conditional formatting if found?

I might possibly want to remove the - and then reformat the string so that i can move the - to the outside of the string... as it's a formatted currency. currently it negative numbers look like this : $-1.00

thanks all~!

Regexp would be overkill.

if (intval($string)<0) {
   echo "<font color=red>$string</font>";
} else {
echo "$string";

thanks so much. built a function out of it, and added it to common.inc.php ... this one is def. going into my bag of tricks. i usually code in coldfusion or asp, and recently have come back to PHP due to client demands... even though PHP was the first ss lang that i took up.....

again thanks, and i have posted the function from it for all to use:

<?
function print_int_colors($string) {
	if (intval($string)<0) { 
	   echo "<font color=red>".$string."</font>"; 
			} else { 
	   echo "<font color=green>".$string."</font>";
	}
}
// usage //
// print_int_colors($variable_thats_negative_or_positive);
?>

stoopid word wrap... but you get the idea....
