Hello, where the error in this code!

where the error in this code! the Q is : Check if each student has a GPA of 4.0. If the student has a GPA of 4.0, use the student's name variable to display "NAME made the Honor Roll". If not, use the variable to display "NAME has a GPA of GPA".

index.php 
<?php
$studentOneName = 'Dave';
$studentOneGPA = 3.8;

$studentTwoName = 'Treasure';
$studentTwoGPA = 4.0;

if ( $studentTwoGPA = 4.0 )
{
 echo  "$studentTwoName made the Honor Roll";
}
else {

  echo "$studentTwoName has a GPA of GPA";
}
?>

In the if statement you are assigning with =.

Compare values with == or ===.

Just to add to the previous comment, you are also missing the value of the GPA variable in the secound echo statement.

The soulution is that: 

<?php
$studentOneName = 'Dave';
$studentOneGPA = 3.8;

$studentTwoName = 'Treasure';
$studentTwoGPA = 4.0;

//Place your code below this comment

if ($studentOneGPA == 4.0) {
  echo "{$studentOneName} made the Honor Roll";
} else {
  echo "{$studentOneName} has a GPA of {$studentOneGPA}";
}

if ($studentTwoGPA == 4.0) {
  echo "{$studentTwoName} made the Honor Roll";
} else {
  echo "{$studentTwoName} has a GPA of {$studentTwoGPA}";
}

?>

So, I investigated all of the students and criteria... :)

why is these '{}' used around the $studentOneName and $studentTwoName?

re: why is these '{}' used around the $studentOneName and $studentTwoName?

I like "${name_of_variable}" full format embeded var in string because:

  • easier recognise that is an embeded variable in string
  • always work, where the normal $varible it doesn't
  • unify my code

Did you change those 2 things?

Here, like this:

<?php
$studentOneName = 'Dave';
$studentOneGPA = 3.8;

$studentTwoName = 'Treasure';
$studentTwoGPA = 4.0;

if ( $studentTwoGPA == 4.0 ) {
    echo  "$studentTwoName made the Honor Roll";
} else {
    echo "$studentTwoName has a GPA of $studentTwoGPA";
}

This gives me the following message on my local machine:

Treasure made the Honor Roll

If I change $studentTwoGPA to 3.9, I get the message:

Treasure has a GPA of 3.9

Bingo Bongo - working! :)

Oh - the question is asking for student 1, not student 2!

Change the 3 lines in the if statement and it should work...

Budoor, you only checked for student two, you have to check for student one also. Hope this helps! :)
