Which loop is faster, while or for?

Question

You can get the same output with for and while loops:

While:

$i = 0;
while ($i <= 10){
  print $i.\"\\n\";
  $i++;
};
         


        

Answer 1

They should be equal. The for loop you wrote is doing exactly the same thing that the while loop is doing: setting $i=0, printing $i, and incrementing $i at the end of the loop.
