I am new at php. I am trying to loop a number in each click of a button. See attached picture for reference.

1 should iterate after the click of the button and will stop to iterate when it gets to 5. 

 

Here is my code:

<!DOCTYPE html> 
<html> 
  <body> 
    <div>Question <?php $num = 5; $n = 1; $n <= $num; echo $n; ?> of <?php echo $num;?></div> 
    <form method="post"> <button id="button" class="button" value="add" name="add">Click</button> </form>
  </body> 
</html>

 

If I try to loop it this way,

<!DOCTYPE html> 
<html> 
  <body> 
    <div>Question <?php $num = 5; for($i = 1; $i <= $num; $i++){ echo $i; } ?> of <?php echo $num;?></div> 
    <form method="post"> <button id="button" class="button" value="add" name="add">Click</button> </form> 
  </body> 
</html>

the result is Question 12345 of 5.

PHP is stateless which means it does not remember what happened previously. To do what you want you will need to keep track of the variables using sessions. It would not be a loop at all. You would need to check and increment a $_SESSION variable on each call.
