How can debugging tools like var_dump() help identify issues in PHP code related to array processing?

Debugging tools like var_dump() can help identify issues in PHP code related to array processing by displaying the structure and values of arrays at specific points in the code. This can help developers pinpoint where the issue lies, such as incorrect array keys or values. By using var_dump() to output the array data, developers can see exactly what is stored in the array and troubleshoot any discrepancies. 

<?php

// Sample array with potential issues
$array = array(
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3'
);

// Using var_dump() to inspect the array
var_dump($array);

// Further code logic to process the array
// ...
?>
