Subject: Do constant evaluation for str_contains in opcache
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=47ddd95836142a5bea28abab26999e72d5f85493;p=php

Do constant evaluation for str_contains in opcache

Both arguments must be strings.
str_contains deliberately does not emit a warning for an empty needle.

Closes GH-5324
