preg_match() returns 0 although regex testers work

I'm trying to validate a string using /[\p{L}\s]{6,}/ and trying to match characters only (Unicode ones as well). I used regex101 to test my regex and it works for the string Владимир Алексић. However, when I use that regex in preg_match() with the same string, it always returns 0. Yet, it returns 1 if I avoid all characters except A-Za-z.

Why is that so?

Proof for regex101

Solution

  • The \p and other escape sequences which work with unicode character properties don't work unless the u pattern modifier is set.

    /[\p{L}\s]{6,}/u
