Why is it recommended to use arrays instead of numbered variables for result sets in PHP?

Using arrays instead of numbered variables for result sets in PHP is recommended because arrays are more flexible and easier to work with when dealing with multiple data entries. Arrays allow for easier iteration, manipulation, and organization of data compared to numbered variables. Additionally, arrays provide a more dynamic way to store and access data, making it easier to handle varying result sets.

// Example of using an array for a result set in PHP
$resultSet = array(
    array('name' => 'John', 'age' => 25),
    array('name' => 'Jane', 'age' => 30),
    array('name' => 'Alice', 'age' => 22)
);

// Accessing data from the result set
foreach($resultSet as $row){
    echo $row['name'] . ' is ' . $row['age'] . ' years old. <br>';
}
