The variable $module_slug 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

  1. 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;
        }
    }
    
  2. 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;
    }
    
  3. Add a value for the missing path:

    function myFunction($a) {
        switch ($a) {
            case 'foo':
                $x = 1;
                break;
    
            case 'bar':
                $x = 2;
                break;

The method activate_module() contains an exit expression.

An exit expression should only be used in rare cases. For example, if you write a short command line script.

In most cases however, using an exit expression makes the code untestable and often causes incompatibilities with other libraries. Thus, unless you are absolutely sure it is required here, we recommend to refactor your code to avoid its usage.

Coding Style Comprehensibility introduced by
$return was never initialized. Although not strictly required by PHP, it is generally a good practice to add $return = 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.

The method admin_page_load() contains an exit expression.

An exit expression should only be used in rare cases. For example, if you write a short command line script.

In most cases however, using an exit expression makes the code untestable and often causes incompatibilities with other libraries. Thus, unless you are absolutely sure it is required here, we recommend to refactor your code to avoid its usage.

5886

5888

	 * - Saves a minimum of 56k
