The variable $method 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.

Bug introduced by
The variable $headers 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.

Comprehensibility Best Practice introduced by
Using logical operators such as or instead of || is generally not recommended.

PHP has two types of connecting operators (logical operators, and boolean operators):

  Logical Operators Boolean Operator
AND - meaning and &&
OR - meaning or ||

The difference between these is the order in which they are executed. In most cases, you would want to use a boolean operator like &&, or ||.

Let’s take a look at a few examples:

// Logical operators have lower precedence:
$f = false or true;

// is executed like this:
($f = false) or true;


// Boolean operators have higher precedence:
$f = false || true;

// is executed like this:
$f = (false || true);

Logical Operators are used for Control-Flow

One case where you explicitly want to use logical operators is for control-flow such as this:

$x === 5
    or die('$x must be 5.');

// Instead of
if ($x !== 5) {
    die('$x must be 5.');
}

Since die introduces problems of its own, f.e. it makes our code hardly testable, and prevents any kind of more sophisticated error handling; you probably do not want to use this in real-world code. Unfortunately, logical operators cannot be combined with throw at this point:

// The following is currently a parse error.
$x === 5
    or throw new RuntimeException('$x must be 5.');

These limitations lead to logical operators rarely being of use in current PHP code.
