Oops! It looks like Task 2 is no longer passing.

Why is Task 2 no longer passing?

index.php 
<?php

//Place your code below this comment

$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;

$integerOne += 5;
$integerTwo -= 1;

$integerOne *= $floatOne;
echo $integerOne;
echo $integerTwo;

?>

Your code for Task 3 should be:

echo $integerOne * $floatOne;

What you’ve done is assign the result of $integerOne * $floatOne back into $integerOne and then echoed $integerOne and $integerTwo.

This:

$integerOne *= $floatOne;

produces the same result as:

$integerOne * $floatOne;

You nailed it bro! Thanks! (Ultimately, the problem was that the challenge course was telling me that Task 2 was no longer passing, but the truth was that I just didn't execute task 3 properly.) Thanks again!

  • You only need to echo one thing here
  • You're not echoing the right thing
  • Looks like the challenge wont accept a solution using the *= operator. Use regular multiplication instead

Let me know if this helps here

Hey Adam! Thank you for taking the time to reply man! The echo of $integerTwo was just me testing things in desperation trying to figure out why task two $integerOne += 5; and $integerTwo -= 1; was no longer valid. I did try using regular multiplication, but that didn't work either. You and Kieran got it right with your posts below - I was assigning the value of $integerOne * $floatOne to $integerOne, rather than just displaying the results of the multiplication problem. Ultimately, the problem was that the challenge course was telling me that Task 2 was no longer passing, but the truth was that I just didn't execute task 3 properly. Thank you so much for your help!
