One somewhat famous hidden landmine is in_array('0010e2', ['1e3']);
And that will return true, because you forgot the third "strict" parameter. This is really something strict_types could/should have fixed, but it doesn't.
You can have code reviews and static analysers and all of that to catch this, but it's definitely a landmine. I've seen some pretty serious CVEs that were fixed just by adding that last parameter to some in_array() call.
