		0 ignored issues – show Documentation Bug introduced 2017-11-09 18:14 UTC by Report Bug Copy Issue Report It seems like `$phpFinder->find()` can also be of type `false`. However, the property `$phpPath` is declared as type `string`. Maybe add an additional type check? Our type inference engine has found a suspicous assignment of a value to a property. This check raises an issue when a value that can be of a mixed type is assigned to a property that is type hinted more strictly. For example, imagine you have a variable `$accountId` that can either hold an Id object or false (if there is no account id yet). Your code now assigns that value to the `id` property of an instance of the `Account` class. This class holds a proper account, so the id value must no longer be false. Either this assignment is in error or a type check should be added for that assignment. class Id { public $id; public function __construct($id) { $this->id = $id; } } class Account { /** @var Id $id */ public $id; } $account_id = false; if (starsAreRight()) { $account_id = new Id(42); } $account = new Account(); if ($account instanceof Id) { $account->id = $account_id; } Loading history...

		0 ignored issues – show Bug Best Practice introduced 2017-11-09 18:14 UTC by Report Bug Copy Issue Report The expression `$this->phpPath` of type `string\|false` is loosely compared to `false`; 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...
