These elseif bodies can be removed. If you have an empty elseif but statements in the else branch, consider inverting the condition.

42% of this comment could be valid code. Did you maybe forget this after debugging?

Sometimes obsolete code just ends up commented out instead of removed. In this case it is better to remove the code once you have checked you do not need it.

The code might also have been commented out for debugging purposes. In this case it is vital that someone uncomments it again or your project may behave in very unexpected ways in production.

This check looks for comments that seem to be mostly valid code and reports them.

Unused Code introduced by
The call to Schema::__construct() has too many arguments starting with $args.

This check compares calls to functions or methods with their respective definitions. If the call has more arguments than are defined, it raises an issue.

If a function is defined several times with a different number of parameters, the check may pick up the wrong definition and report false positives. One codebase where this has been known to happen is Wordpress.

In this case you can add the @ignore PhpDoc annotation to the duplicate definition and it will be ignored.

Documentation introduced by
$value is of type null|false, but the function expects a array.

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
The variable $type 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;
    }

Unused Code introduced by
This if statement is empty and can be removed.

This check looks for the bodies of if statements that have no statements or where all statements have been commented out. This may be the result of changes for debugging or the code may simply be obsolete.

These if bodies can be removed. If you have an empty if but statements in the else branch, consider inverting the condition.

if (rand(1, 6) > 3) {
//print "Check failed";
} else {
    print "Check succeeded";
}

could be turned into

if (rand(1, 6) <= 3) {

}

This is much more concise to read.

Equals sign not aligned with surrounding assignments; expected 3 spaces but found 1 space

This check looks for multiple assignments in successive lines of code. It will report an issue if the operators are not in a straight line.

To visualize

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

will produce issues in the first and second line, while this second example

Equals sign not aligned with surrounding assignments; expected 6 spaces but found 1 space

This check looks for multiple assignments in successive lines of code. It will report an issue if the operators are not in a straight line.

To visualize

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

will produce issues in the first and second line, while this second example

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

will produce no issues.

This if statement is empty and can be removed.

This check looks for the bodies of if statements that have no statements or where all statements have been commented out. This may be the result of changes for debugging or the code may simply be obsolete.

These if bodies can be removed. If you have an empty if but statements in the else branch, consider inverting the condition.

if (rand(1, 6) > 3) {
//print "Check failed";
} else {
    print "Check succeeded";
}

could be turned into

if (rand(1, 6) <= 3) {

This is much more concise to read.

As per coding style, self should be used for accessing local static members.

This check looks for accesses to local static members using the fully qualified name instead of self::.

While this is perfectly valid, the fully qualified name of Certificate::TRIPLEDES_CBC could just as well be replaced by self::TRIPLEDES_CBC. Referencing local members with self:: assured the access will still work when the class is renamed, makes it perfectly clear that the member is in fact local and will usually be shorter.

$errorCount is not used, you could remove the assignment.

This check looks for variable assignements that are either overwritten by other assignments or where the variable is not used subsequently.

$myVar = 'Value';

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.
