			0 ignored issues – show Coding Style Comprehensibility introduced 2019-09-06 14:53 UTC by Report Bug Copy Issue Report `$parameters` was never initialized. Although not strictly required by PHP, it is generally a good practice to add `$parameters = array();` before regardless. Adding an explicit array definition is generally preferable to implicit array definition as it guarantees a stable state of the code. Let’s take a look at an example: foreach ($collection as $item) { $myArray['foo'] = $item->getFoo(); if ($item->hasBar()) { $myArray['bar'] = $item->getBar(); } // do something with $myArray } As you can see in this example, the array `$myArray` is initialized the first time when the foreach loop is entered. You can also see that the value of the `bar` key is only written conditionally; thus, its value might result from a previous iteration. This might or might not be intended. To make your intention clear, your code more readible and to avoid accidental bugs, we recommend to add an explicit initialization `$myArray = array()` either outside or inside the foreach loop.

			0 ignored issues – show Bug introduced 2019-09-06 14:53 UTC by Report Bug Copy Issue Report The variable `$parameters` does not seem to be defined for all execution paths leading up to this point. If you define a variable conditionally, it can happen that it is not defined for all execution paths. Let’s take a look at an example: function myFunction($a) { switch ($a) { case 'foo': $x = 1; break; case 'bar': $x = 2; break; } // $x is potentially undefined here. echo $x; } In the above example, the variable `$x` is defined if you pass “foo” or “bar” as argument for `$a`. However, since the `switch` statement has no default case statement, if you pass any other value, the variable `$x` would be undefined. Available Fixes Check for existence of the variable explicitly: function myFunction($a) { switch ($a) { case 'foo': $x = 1; break; case 'bar': $x = 2; break; } if (isset($x)) { // Make sure it's always set. echo $x; } } Define a default value for the variable: function myFunction($a) { $x = ''; // Set a default which gets overridden for certain paths. switch ($a) { case 'foo': $x = 1; break; case 'bar': $x = 2; break; } echo $x; } Add a value for the missing path: function myFunction($a) { switch ($a) { case 'foo': $x = 1; break; case 'bar': $x = 2; break; // We add support for the missing case. default: $x = ''; break; } echo $x; } Loading history...

			0 ignored issues – show Documentation Bug introduced 2016-12-15 20:35 UTC by Report Bug Copy Issue Report It seems like `$data` can be `null`. However, the property `$lastTokenCredentialsResponse` is declared as `array`. Maybe change the type of the property to `array\|null` or add a type check? Our type inference engine has found an assignment of a scalar value (like a string, an integer or null) to a property which is an array. Either this assignment is in error or the assigned type should be added to the documentation/type hint for that property. To type hint that a parameter can be either an array or null, you can set a type hint of array and a default value of null. The PHP interpreter will then accept both an array or null for that parameter. function aContainsB(array $needle = null, array $haystack) { if (!$needle) { return false; } return array_intersect($haystack, $needle) == $haystack; } The function can be called with either null or an array for the parameter `$needle` but will only accept an array as `$haystack`.
