			0 ignored issues – show Bug introduced 2017-03-15 10:42 UTC by Report Bug Copy Issue Report Are you sure the assignment to `$pid` is correct as `$this->sendSignal(SIGTERM)` (which targets `Laravoole\Commands\LaravooleCommand::sendSignal()`) seems to always return null. This check looks for function or method calls that always return null and whose return value is assigned to a variable. class A { function getObject() { return null; } } $a = new A(); $object = $a->getObject(); The method `getObject()` can return nothing but null, so it makes no sense to assign that value to a variable. The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes. Loading history...

			0 ignored issues – show Bug Best Practice introduced 2017-03-15 10:42 UTC by Report Bug Copy Issue Report The expression `$this->getPid()` of type `string\|false` 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...
