I'm going to break your code down into some smaller chunks so it's easier for you to understand.

First, var_dump is used to dump the contents of a variable and to my knowledge cannot be used for evaluation. Change your var dump to the following:

var_dump ($studentOneGPA);

Second, you're using an if else improperly. When using just an else statement, you cannot provide any parameters, only an else if can contain comparison. Change your if else to the following:

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

The final issue here is that you're essentially checking for the same thing in both the initial condition and the else if condition. You should always check for different values when running an if else Change it to the following:

// Only gets run if the GPA is equal to 4.0 otherwise the else if is run if the GPA is below 4.0
if ($studentTwoGPA == 4.0) {
  echo "$studentTwoName made the Honor Roll";
} else if ($studentOneGPA < 4.0) {
  echo "$studentOneName has a GPA of GPA";
}
