How can debugging techniques like var_dump() be used to troubleshoot issues with PHP return arrays?

When troubleshooting PHP return arrays, debugging techniques like var_dump() can be used to inspect the contents of the array and identify any issues such as missing or incorrect data. By using var_dump() to print out the array, you can see the structure and values of the array elements, helping you pinpoint where the problem lies. This can be especially useful when dealing with complex multidimensional arrays or when trying to understand the data being returned from a function or API.

// Example code snippet using var_dump() to troubleshoot PHP return arrays

// Sample array with potential issues
$myArray = array(
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'johndoe@example.com'
);

// Debugging the array using var_dump()
var_dump($myArray);
