What advice is given regarding the use of a do while loop in PHP?

When using a do-while loop in PHP, it is important to ensure that the loop will execute at least once before checking the condition for continuation. This is because the code block inside the loop will always run at least once before the condition is evaluated. Be cautious when using a do-while loop to avoid infinite loops if the condition is never met. 

$counter = 0;

do {
    echo "The counter is: $counter <br>";
    $counter++;
} while ($counter < 5);
