Preg_match with fullwidth numbers

Question

I'm trying to do some validation exercises and I was wondering this code seems to return false always.

if (preg_match("/^[０-９]{7}$/", '１２３４５６７')) {
    die('match');
}

I'm currently testing for full-width japanese characters/numbers. I'm wondering why it doesn't execute the die command. Any help is appreciated. Thank you in advance :)

`Warning: preg_match(): Compilation failed: missing closing parenthesis`. Remove `(`, use `"/^[０-９]{7}$/"` — Wiktor Stribiżew, Dec 03 '18 at 10:58
Now, you just need to add `u` modifier. See https://3v4l.org/fGtsQ — Wiktor Stribiżew, Dec 03 '18 at 11:05
