How can the var_dump() function be helpful in debugging PHP array structures?

The var_dump() function can be helpful in debugging PHP array structures by providing detailed information about the contents and structure of the array. This can help identify any unexpected values, keys, or nested arrays within the array structure, making it easier to pinpoint and resolve any issues with the data. 

<?php
// Sample array structure for debugging
$array = array(
    'key1' => 'value1',
    'key2' => array(
        'nested_key1' => 'nested_value1',
        'nested_key2' => 'nested_value2'
    ),
    'key3' => 'value3'
);

// Debugging the array structure using var_dump()
var_dump($array);
?>
