How can setting variables and using them in for loops impact the functionality of PHP code?

Setting variables and using them in for loops can impact the functionality of PHP code by allowing for more dynamic control over loop iterations. This can help make the code more readable and maintainable by storing values that are reused within the loop. By setting variables outside of the loop and using them within the loop, you can avoid redundancy and potential errors that may arise from manually repeating values. 

// Example of setting variables and using them in a for loop
$start = 1;
$end = 5;

for ($i = $start; $i <= $end; $i++) {
    echo "Iteration: $i\n";
}
