Question

i want to compare a number in 3 areas

for example:

when $a is > 0 and < 80 echo RED

when $a is > 80 and < 100 echo YELLOW

when $a is > 100 echo RED

the problem with my code now is: when $a=80 i got no result

here is my code:

<?php

$a=80;

if(($a > 0) && ($a < 80))
{
echo('RED');
}
if(($a > 80) && ($a < 100))
{
echo('YELLOW');
}
if($a > 100)
{
echo('GREEN');
}

?>

you can see the test with $a=79 here

and with $a=80 here

how can i realize this? maybe in a smaller and nicer way 😀

don’t know if it’s important.. but $a can be 80.1 and can be bigger than 100

Answer 1

You need to determine which color you want 80 to be. in this example I’ll make it RED

$a=80;

if(($a > 0) && ($a <= 80)){
    echo('RED');
}elseif(($a > 80) && ($a < 100)){
    echo('YELLOW');
}elseif($a > 100){
    echo('GREEN');
}

Do you notice the = in $a <= 80

Additionally, you will run into the same problem with 100 and 0 so you will need to deal with those as well.
