Question

I have a string “Mod. 816-10 025” and I want to remove everything but the 816-10.

Conditions:

• The number in the center will always be ###-##
• It may not be 3 numbers – 2 numbers but it will always be space numbers dash numbers space

Can someone help me? I’ve tried like 5 different regex but no success.

Answer 1

If the conditions always remain, there is no need for RegEx:

$string = explode(" ","Mod. 816-10 025");
$number = $string[1];

Note: Using php native functions will usually be faster than the powerful RegEx.
