By comparing
$agentto the empty strict with loose equivalence (==) instead of strict equality (===), this permits matching more than just the empty string, according to the PHP type comparison truth table. Specifically,$agentwill also match if it contains the string"0", rather than being empty, which I believe should be regarded as a false positive.
