What potential pitfalls should be considered when assigning and retrieving multiple values in PHP?

When assigning and retrieving multiple values in PHP, it's important to ensure that the number of values being assigned matches the number of variables receiving them. Failure to do so can result in unexpected behavior or errors in your code. To avoid this, you can use list() or [] syntax to assign multiple values to variables and ensure consistency when retrieving them. 

// Assigning multiple values using list()
$data = [1, 2, 3];
list($a, $b, $c) = $data;

// Retrieving multiple values using []
$data = ['name' => 'John', 'age' => 30];
$name = $data['name'];
$age = $data['age'];
