How can PHP developers optimize their code to avoid storing all database values in separate arrays when using mysql_fetch_array?

When using mysql_fetch_array in PHP, developers can optimize their code by fetching each row from the database one at a time instead of storing all the values in separate arrays. This can help reduce memory usage and improve performance by processing the data as it is retrieved from the database. 

// Connect to the database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Query the database
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);

// Fetch and process each row one at a time
while ($row = mysqli_fetch_array($result)) {
    // Process the data from the current row
    echo $row['column1'] . ' - ' . $row['column2'] . '<br>';
}

// Close the connection
mysqli_close($connection);
