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

It shouldn't matter which is faster. If it does matter then benchmark it using your real code and see for yourself.
