		0 ignored issues – show Bug introduced 2015-12-31 20:10 UTC by Report Bug Copy Issue Report The variable `$default` seems to never exist, and therefore `empty` should always return `true`. Did you maybe rename this variable? This check looks for calls to `isset(...)` or `empty()` on variables that are yet undefined. These calls will always produce the same result and can be removed. This is most likely caused by the renaming of a variable or the removal of a function/method parameter. Loading history...

		0 ignored issues – show Bug introduced 2015-12-31 20:10 UTC by Report Bug Copy Issue Report The variable `$module` seems only to be defined at a later point. Did you maybe move this code here without moving the variable definition? This error can happen if you refactor code and forget to move the variable initialization. Let’s take a look at a simple example: function someFunction() { $x = 5; echo $x; } The above code is perfectly fine. Now imagine that we re-order the statements: function someFunction() { echo $x; $x = 5; } In that case, `$x` would be read before it is initialized. This was a very basic example, however the principle is the same for the found issue. Loading history...

		0 ignored issues – show Bug introduced 2015-12-31 20:10 UTC by Report Bug Copy Issue Report The variable `$module` does not seem to be defined for all execution paths leading up to this point. If you define a variable conditionally, it can happen that it is not defined for all execution paths. Let’s take a look at an example: function myFunction($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...
