How can var_export() be utilized to understand and troubleshoot code involving arrays in PHP?

To understand and troubleshoot code involving arrays in PHP, you can use var_export() to display the structure and values of an array. This can help you identify any issues with the array such as missing or incorrect values, unexpected keys, or nested arrays. By using var_export() to print out the array, you can easily see its contents and debug any problems.

$array = ['foo' => 'bar', 'baz' => ['qux', 'quux']];
echo '<pre>';
var_export($array);
echo '</pre>';
