Coding Style introduced by
The visibility should be declared for property $instance.

The PSR-2 coding standard requires that all properties in a class have their visibility explicitly declared. If you declare a property using

class A {
    var $property;
}

the property is implicitly global.

To learn more about the PSR-2, please see the PHP-FIG site on the PSR-2.

Security Best Practice introduced by
It seems like you do not handle an error condition here. This can introduce security issues, and is generally not recommended.

If you suppress an error, we recommend checking for the error condition explicitly:

// For example instead of
@mkdir($dir);

// Better use
if (@mkdir($dir) === false) {
    throw new \RuntimeException('The directory '.$dir.' could not be created.');

Coding Style introduced by
Equals sign not aligned correctly; expected 1 space but found 2 spaces

This check looks for improperly formatted assignments.

Every assignment must have exactly one space before and one space after the equals operator.

To illustrate:

$a = "a";
$ab = "ab";
$abc = "abc";

will have no issues, while

$a   = "a";
$ab  = "ab";
$abc = "abc";

will report issues in lines 1 and 2.

Bug introduced by
The variable $query_args does not exist. Did you forget to declare it?

This check marks access to variables or properties that have not been declared yet. While PHP has no explicit notion of declaring a variable, accessing it before a value is assigned to it is most likely a bug.

Documentation introduced by
Should the type for parameter $old_roles not be array|null?

This check looks for @param annotations where the type inferred by our type inference engine differs from the declared type.

It makes a suggestion as to what type it considers more descriptive.

Most often this is a case of a parameter that can be null in addition to its declared types.

Bug Best Practice introduced by
The expression $network_plugins of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent.

Consider making the comparison explicit by using empty(..) or ! empty(...) instead.

Documentation introduced by
JETPACK__VERSION is of type string, but the function expects a boolean.

It seems like the type of the argument is not accepted by the function/method which you are calling.

In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug.

We suggest to add an explicit type cast like in the following example:

function acceptsInteger($int) { }

$x = '123'; // string "123"

// Instead of
acceptsInteger($x);

// we recommend to use
acceptsInteger((integer) $x);

Coding Style Compatibility introduced by
The method activate_new_modules() 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.

Bug Best Practice introduced by
The expression $replacement of type null|string is loosely compared to true; this is ambiguous if the string can be empty. You might want to explicitly use !== null 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

Bug Best Practice introduced by
The expression $deactivated of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent.

Consider making the comparison explicit by using empty(..) or ! empty(...) instead.

Coding Style Compatibility introduced by
The method activate_default_modules() 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.

Equals sign not aligned correctly; expected 1 space but found 4 spaces

This check looks for improperly formatted assignments.

Every assignment must have exactly one space before and one space after the equals operator.

To illustrate:

$a = "a";
$ab = "ab";
$abc = "abc";

will have no issues, while

$a   = "a";
$ab  = "ab";
$abc = "abc";

will report issues in lines 1 and 2.

Documentation introduced by
false is of type boolean, but the function expects a string|null.

It seems like the type of the argument is not accepted by the function/method which you are calling.

In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug.

We suggest to add an explicit type cast like in the following example:

function acceptsInteger($int) { }

$x = '123'; // string "123"

// Instead of
acceptsInteger($x);

// we recommend to use
acceptsInteger((integer) $x);

Coding Style Compatibility introduced by
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.

false is of type boolean, but the function expects a string|null.

It seems like the type of the argument is not accepted by the function/method which you are calling.

In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug.

We suggest to add an explicit type cast like in the following example:

function acceptsInteger($int) { }

$x = '123'; // string "123"

// Instead of
acceptsInteger($x);

// we recommend to use
acceptsInteger((integer) $x);

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.

Both the $myVar assignment in line 1 and the $higher assignment in line 2 are dead. The first because $myVar is never used and the second because $higher is always overwritten for every possible time line.

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

Bug introduced by
The variable $activated_manage 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;
    
            // We add support for the missing case.
            default:
                $x = '';
                break;
        }
    
        echo $x;
    }

Bug Best Practice introduced by
The expression $deactivated_titles of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent.

Consider making the comparison explicit by using empty(..) or ! empty(...) instead.

Security Best Practice introduced by
It seems like you do not handle an error condition here. This can introduce security issues, and is generally not recommended.

If you suppress an error, we recommend checking for the error condition explicitly:

// For example instead of
@mkdir($dir);

// Better use
if (@mkdir($dir) === false) {
    throw new \RuntimeException('The directory '.$dir.' could not be created.');

Documentation introduced by
$user_id is of type integer, but the function expects a boolean.

It seems like the type of the argument is not accepted by the function/method which you are calling.

In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug.

We suggest to add an explicit type cast like in the following example:

function acceptsInteger($int) { }

$x = '123'; // string "123"

// Instead of
acceptsInteger($x);

// we recommend to use
acceptsInteger((integer) $x);

Bug introduced by
There is no parameter named $result. Was it maybe removed?

This check looks for PHPDoc comments describing methods or function parameters that do not exist on the corresponding method or function.

Consider the following example. The parameter $italy is not defined by the method finale(...).

/**
 * @param array $germany
 * @param array $island
 * @param array $italy
 */
function finale($germany, $island) {
    return "2:1";
}

The most likely cause is that the parameter was removed, but the annotation was not.

Unused Code introduced by
The assignment to $envToken is unused. Consider omitting it like so list($first,,$third).

This checks looks for assignemnts to variables using the list(...) function, where not all assigned variables are subsequently used.

Consider the following code example.

<?php

function returnThreeValues() {
    return array('a', 'b', 'c');
}

list($a, $b, $c) = returnThreeValues();

print $a . " - " . $c;

Only the variables $a and $c are used. There was no need to assign $b.

Instead, the list call could have been.

There is no parameter named $result. Was it maybe removed?

This check looks for PHPDoc comments describing methods or function parameters that do not exist on the corresponding method or function.

Consider the following example. The parameter $italy is not defined by the method finale(...).

/**

The most likely cause is that the parameter was removed, but the annotation was not.
