		0 ignored issues – show Bug Best Practice introduced 2016-09-02 15:11 UTC by Report Bug Copy Issue Report The expression `$year` 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...

		0 ignored issues – show Security Bug introduced 2016-09-02 15:11 UTC by Report Bug Copy Issue Report It seems like `$version` defined by `$this->getMagentoVersion($response)` on line `43` can also be of type `false`; however, `MageScan\Check\Version\D...itionByYearAndVersion()` does only seem to accept `string`, did you maybe forget to handle an error condition? This check looks for type mismatches where the missing type is `false`. This is usually indicative of an error condtion. Consider the follow example <?php function getDate($date) { if ($date !== null) { return new DateTime($date); } return false; } This function either returns a new `DateTime` object or false, if there was an error. This is a typical pattern in PHP programming to show that an error has occurred without raising an exception. The calling code should check for this returned `false` before passing on the value to another function or method that may not be able to handle a `false`. Loading history...
