How can the var_dump function help in debugging array indexing issues in PHP?

When debugging array indexing issues in PHP, the var_dump function can be used to display the contents of the array and its structure. This can help identify if the array is multidimensional, if the keys are numerical or associative, and if the desired index exists or not. By using var_dump, developers can easily see the array's structure and values, making it easier to pinpoint and resolve indexing problems. 

// Example code demonstrating the use of var_dump in debugging array indexing issues
$array = array(
    "first" => "apple",
    "second" => "banana",
    "third" => "cherry"
);

var_dump($array);
