			0 ignored issues – show Bug Best Practice introduced 2017-12-23 10:08 UTC by Report Bug Copy Issue Report The expression `$autoloader` of type `null\|string` is loosely compared to `false`; this is ambiguous if the string can be empty. 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...
