			0 ignored issues – show Bug Best Practice introduced 2022-07-06 17:28 UTC by Report Bug Copy Issue Report The expression `$sessionCourseSubscriptionId` of type `integer\|null` is loosely compared to `true`; this is ambiguous if the integer can be 0. 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 `integer` values, zero is a special case, in particular the following results might be unexpected: 0 == false // true 0 == null // true 123 == false // false 123 == null // false // It is often better to use strict comparison 0 === false // false 0 === null // false Loading history...
