preg_match(): Compilation failed: nothing to repeat at offset 1 in laravel

Question

preg_match():Compilation failed in my code.

Preg match expression in my controller is

   'phoneno' => 'required|regex:/(+92)[0-9]{10}/',

Please tell me what is wrong with the regex.

Answer 1

You need to escape the + character. You want to match on a phone number starting with +92 . But the + character means that it expects 1 or more of the preceding character . Which in this case you don't want.

So in short, change it to this:

/(\\+92)[0-9]{10}/
