PHP7.2 A non-numeric value encountered

Question

the following part of my code worked fine under PHP7.0:

if (Config::LOG_LEVEL == 'debug' | 'basic' | 'light') {}

I have now updated to PHP7.2 and the following error message appears:

A non-numeric value encountered

does anyone have any idea how i can fix this bug?

`Config::LOG_LEVEL` is probably an integer, and you are comparing it to a string. By the way, you are using bitwise operator on strings. — Zak, Mar 01 '19 at 09:53
You CAN'T compare one value with a multiple of other values like that. You can only compare one value with **one** other value. If you need to check multiple values, you need to make multiple comparisons and connect them with an `OR` logical expression (`OR` or `||` in PHP). — Charlotte Dunois, Mar 01 '19 at 10:21
_“the following part of my code worked fine under PHP7.0”_ - no, it didn’t: https://3v4l.org/urFQe - doesn’t even return true, when `Config::LOG_LEVEL` is (effectively) `basic` or `light`. _Only_ for `debug` this did what you thought it would to begin with. — 04FS, Mar 01 '19 at 11:54

As commented by others already, the code won't work as expected (usage of bitwise operator). Try in_array() instead.

in_array(Config::LOG_LEVEL, ['debug', 'basic', 'light'])
