A PHP substring issue

Question

I got a simple php issue which is that I don't know how to use substring here...

ABCDEF[RAND NUMBER 1-10000000]GH

And so I need to get that random number using substring,

I dont know if my brain works correctly today but I really couldnt figure how to do that.

Answer 1

Regex is always better in this case but If your string pattern is fixed like ABCDEF123456GH, you can simply use substr like

$str = "ABCDEF432465GH";
echo substr($str, 6, -2);
