How can the var_export function in PHP be utilized to debug and troubleshoot issues with array structures?

When debugging array structures in PHP, the var_export function can be used to display the structure of an array in a human-readable format. This can help identify any issues such as missing or incorrect values, keys, or nested arrays. By using var_export, developers can quickly visualize the array structure and pinpoint any problems that may be causing unexpected behavior. 

// Example array to debug
$array = [
    'key1' => 'value1',
    'key2' => [
        'nested_key1' => 'nested_value1',
        'nested_key2' => 'nested_value2'
    ]
];

// Display array structure using var_export
echo '<pre>';
var_export($array);
echo '</pre>';
