What if the string is `calculate 155 x 55 + 4`? What numbers then? – Qirel Jul 04 '19 at 12:30

Maybe a regex? What have you tried? What are example strings? Possibly `(\d+)\h+x\h+(\d+)` – user3783243 Jul 04 '19 at 12:31

You can use regex for this.
Regex will match and capture in strings according to a pattern, in this case the pattern is a simple any size digit.
preg_match_all("/(\d+)/", $string, $matches);
list($number1, $number2) = $matches[1];
The regex will capture any number of numbers in the string ("155 x 25 x 40" for example), but the list() function is the limiting factor here.
If there is three numbers in the list() will fail.
So I recommend you to use the array instead of the list($number1, $number2).
