Are there any best practices or idioms for assigning values from an array to variables in PHP?

When assigning values from an array to variables in PHP, it is important to ensure that the array key exists before attempting to assign it to a variable. One common approach is to use the `isset()` function to check if the key exists in the array before assigning its value to a variable. This helps prevent errors or warnings when accessing undefined array keys. 

// Sample array
$data = ['name' => 'John', 'age' => 30, 'city' => 'New York'];

// Assign values from array to variables
$name = isset($data['name']) ? $data['name'] : null;
$age = isset($data['age']) ? $data['age'] : null;
$city = isset($data['city']) ? $data['city'] : null;

// Output variables
echo "Name: $name, Age: $age, City: $city";
