What are the advantages of using associative array keys in PHP over numeric indexes, especially when accessing database query results?

When accessing database query results in PHP, using associative array keys instead of numeric indexes allows for more meaningful and easier to understand code. Associative array keys provide context to the data being accessed, making the code more readable and maintainable. Additionally, associative array keys allow for flexibility in the structure of the data, as they are not tied to a specific numerical order. 

// Example of fetching data from a database query using associative array keys
$query = "SELECT id, name, email FROM users";
$result = mysqli_query($connection, $query);

while ($row = mysqli_fetch_assoc($result)) {
    echo "ID: " . $row['id'] . " | Name: " . $row['name'] . " | Email: " . $row['email'] . "<br>";
}
