What are the potential pitfalls of creating multiple variables in a for-loop in PHP?

Creating multiple variables in a for-loop in PHP can lead to confusion and potential errors, especially if the variables are not properly scoped or initialized within the loop. To avoid this, it's recommended to declare and initialize variables outside of the loop and then use them within the loop. 

// Declare and initialize variables outside of the loop
$start = 1;
$end = 10;

// Use variables within the loop
for ($i = $start; $i <= $end; $i++) {
    // Loop logic here
}
