20,008 PointsI believe I found a bug in the PHP basics course
Hello Alena Holligan , I think I found a bug in task 3 of this exercise:
https://teamtreehouse.com/library/php-basics-2/unit-converter/manipulating-numbers
The error I get is: "Are you sure you multiplied $integerOne by $floatOne? This should be the same as 6*1.5 which equals 9."
While my code is:
<?php
//Place your code below this comment
// Task One:
$integerOne = 1;
$integerTwo = 2;
// Task two:
$integerOne += 5;
$integerTwo -= 1;
echo $integerOne;
echo $integerTwo;
// Task three:
$floatOne = 1.5;
echo $integerOne * $floatOne;
?>
I also tried to put the multiplication in a "result" variable (I thought this is an expected architecture) but I still have the same error.
There is a another error, but a similar problem when two first echos are var_dumps.

This is due to the fact that in addition to using echo to show the result of $integerOne * $floatOne you also use echo earlier in the code to display the contents of $integerOne and $integerTwo. Which is not something the challenge asked you to do.
If you remove those additional echo statements like this:
<?php
//Place your code below this comment
// Task One:
$integerOne = 1;
$integerTwo = 2;
// Task two:
$integerOne += 5;
$integerTwo -= 1;
// Removed two echo statements from this section
// Task three:
$floatOne = 1.5;
echo $integerOne * $floatOne;
?>
Then your code will work. Challenges are very picky, so adding anything not explicitly asked for will often lead to the challenge failing even if your code is otherwise correct.

20,008 PointsOh, this is quite strange because even when these where printed via var_dump, it still didn't work... But when I removed the echo (or var_dumps) it did work. Thank you!

Treehouse Teacheryes, you cannot add anything else to the output. Having an additional echo or var_dump will not give the desired results. It's always a good idea to remove that extra output, you wouldn't want that showing in production. Trust me I know ;)
