I want to extract the digits from a string that contains numbers and letters like:
"In My Cart : 11 items"
I want to extract the number 11.
11
If you just want to filter everything other than the numbers out, the easiest is to use filter_var:
$str = 'In My Cart : 11 items'; $int = (int) filter_var($str, FILTER_SANITIZE_NUMBER_INT);
