In other cases, however this might be a bug.

Bug Best Practice introduced 2017-03-13 17:07 UTC by Report Bug Copy Issue Report The expression `$this->checkPartMatchingType($queryPart, $type)` 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...

You might want to explicitly use `!== null` instead. In PHP, under loose comparison (like `==`, or `!=`, or `switch` conditions), values of different types might be equal. For `string` values, the empty string `''` is a special case, in particular the following results might be unexpected: '' == false // true '' == null // true 'ab' == false // false 'ab' == null // false // It is often better to use strict comparison '' === false // false '' === null // false Loading history...
