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