Matching 2 items in a string
Little lost here, I am trying to search a line for both values after the $ signs. My ultimate goal is to get percertage.

PHP Code:
<?php
$string = "Something on sale for $4 and orginal price $10";
$strstr =. strstr($string, '$');
$strrchr =. strrchr($string, '$'); 
echo "$strstr<br>";
echo "$strrchr<br>";
//
//echo substr('$strstr', 1, 3);
//echo substr('$strrchr', 1, 3);
?>
Desired result, $1 = 4 and $2 = 10

Not sure how to accomplish this, str or preg_match.

Thanks

I'd suggest using preg_match, Think about your price formats to as you might want to support some or all of the following:

Code:
$ 4
$2,300.50
$2,300
