How can one ensure that the output in a while loop in PHP is consistent across multiple iterations?

When working with a while loop in PHP, it is important to ensure that the output remains consistent across multiple iterations. One way to achieve this is by properly initializing any variables that are being used within the loop to hold the output. By initializing variables outside of the loop and updating them within the loop, you can ensure that the output remains consistent throughout the iterations. 

$output = ''; // Initialize output variable outside the loop

$i = 0;
while ($i < 5) {
    $output .= "Iteration: $i\n"; // Update output variable within the loop
    $i++;
}

echo $output;
