The PHP for Loop

for loop is used when you know in advance how many times the script should run.

for (init counter; test counter; increment counter) {
  code to be executed for each iteration;

init counter: Initialize the loop counter value
test counter: Evaluated for each loop iteration. If it evaluates to TRUE, the loop continues. If it evaluates to FALSE, the loop ends.
increment counter: Increases the loop counter value

for ($k = 0; $k <= 10; $k++) {
  echo "Number is: $k <br>";
