			0 ignored issues – show Bug Best Practice introduced 2018-05-13 20:40 UTC by Report Bug Copy Issue Report The expression `$needed_profile` of type `false\|string` is loosely compared to `true`; this is ambiguous if the string can be empty. You might want to explicitly use `!== false` 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...
