		0 ignored issues – show Bug Best Practice introduced 2015-11-22 19:57 UTC by Report Bug Copy Issue Report The expression `$success` of type `boolean\|null` is loosely compared to `false`; this is ambiguous if the boolean can be false. You might want to explicitly use `!== null` instead. If an expression can have both `false`, and `null` as possible values. It is generally a good practice to always use strict comparison to clearly distinguish between those two values. $a = canBeFalseAndNull(); // Instead of if ( ! $a) { } // Better use one of the explicit versions: if ($a !== null) { } if ($a !== false) { } if ($a !== null && $a !== false) { } Loading history...
