How can basic understanding of arrays in PHP help in resolving issues related to variable assignment and data retrieval?

When dealing with variable assignment and data retrieval in PHP, understanding arrays can be crucial. Arrays allow you to store multiple values in a single variable, which can be especially helpful when working with large sets of data. By using arrays, you can easily assign and retrieve values without having to create multiple individual variables. 

// Example of using arrays to assign and retrieve data
$data = array(
    'name' => 'John',
    'age' => 30,
    'city' => 'New York'
);

// Assigning a new value to the 'age' key
$data['age'] = 31;

// Retrieving the value of the 'city' key
$city = $data['city'];

echo $city; // Output: New York
