foreach.emptyArray

Code example

<?php declare(strict_types = 1);

/** @var array{} $items */
$items = [];

foreach ($items as $item) {
    echo $item;
}

Why is it reported?

The expression passed to foreach is an empty array. The loop body will never execute, making it dead code. This usually indicates a logic error where the array was meant to be populated before the loop.

How to fix it

Make sure the array is populated before iterating, or remove the dead loop:

 <?php declare(strict_types = 1);

-/** @var array{} $items */
-$items = [];
+$items = getItems();

 foreach ($items as $item) {
     echo $item;
 }
