I need help with my code... Thank you.

<?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 GPA"; }

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

?>

index.php 
<?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 GPA";
}

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

You're almost done with this task . All you have to do is : in the echo statement replace the the word GPA with variable $studentOneGPA in the first if statement and the second $studentTwoGPA so you can know what grade he or she has gained if their grade is not equal to 4.0. And it will look like this in the index.php <?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";
}

?>

write echo statements like this. Place the variable without "". Then add the + sign to add the 2 together echo $studentOneName + "made the Honor Roll"; echo $studentOneName + "has a GPA of $studentOneGPA";

As I remember, the "." is used as concatenation symbol in PHP:

echo $variable1 . "String" . $variable2 ;
