What is the purpose of setting a helper counter in a PHP loop and how can it affect the loop's behavior?

Setting a helper counter in a PHP loop can be useful when you need to keep track of the loop's progress or perform certain actions based on the iteration count. It can affect the loop's behavior by allowing you to control how many times the loop should run or by enabling you to execute specific code based on the counter's value.

php 
// Example of using a helper counter in a PHP loop
$counter = 0;
$limit = 5;

while ($counter < $limit) {
    // Loop body
    echo "Iteration: " . ($counter + 1) . "\n";
    
    // Increment the counter
    $counter++;
}
