IF THEN PHP, tough time

[dakotaboy99]

Hello, Im new to the fourm, and just started taking a intro programming class and cant figure this php out, any help?

 

 

Create a PHP program that allows the user to enter in an integer

value that represents the score of a test. Valid integer values are from 0 to 100

inclusive. Display the score (integer value) and the corresponding letter grade. The

grade scale is 10 points.

100 – 90 A

89 – 80 B

79 – 70 C

69 -60 D

Less than 59 F

<?php

$score = 79;

Echo “$score”;

if ($score > 89){

$letter = “A”;

}elseif ($score > 79){

$letter = “ B”;

}

elseif ($score > 69){

$letter = “ C”;

}

elseif ($score > 59){ or <

$letter = “ D”;

>?

This is how our teacher started it off and whanted us to finish

What if your score is 3 ?

<?php $score = 79; Echo “$score”; IF ($score > 89){ $letter = “A”;}ELSE IF ($score > 79){ $letter = “ B”;}ELSE IF ($score > 69){ $letter = “ C”;}ELSE IF ($score > 59){ $letter = “ D”;>?

 

Not sure, the teacher didnt really teach us much, he basically said to teach yourself this problem, everyone in class didnt understand this

please use code tags, I can't tell if you are just copy pasting incorrectly or your ending php tag is really broken.

 

also, please tell us the problem is. what value are you expecting for $letter? what is actually happening?

 

You start with score at 79. But you never test if the score could be 79 (or 89, or 69, etc). Make sure you understand your comparison operators.
