Hello,
I was just wondering after writting the code in version 2 here below, it
turns
out in testing that it actually PHP is not validating the expressions
instead
always I get the first case.
1.Using nested if statement {THE INTENDED BEHAVIOR}:
if ($count > 14)
$boxes = 3;
elseif($count > 7 && $count <= 14)
You don't need the count<=14 part as you will *only* get there if
$count<=14.
$boxes = 2;
else
$boxes = 1;
2. Using Switch {ALWAYS FIRST CASE!!!}
// $boxes = 1;
// switch ($count) {
// case ($count > 14):
// $boxes = 3;
// break;
// case ($count > 7 && $count <= 14):
// $boxes = 2;
// break;
// case ($count <= 7):
// default :
// $boxes = 1;
// break;
// }
Does anyone know the answer why using the Switch it always execute the
first
case ?
As has been pointed out you need switch(true).
That's a strange way of writing a switch, IMO. You should be using the if
version.

Maybe I'm way out of touch, but when I look at php.net for the syntax of the
switch statement I see:
switch($var){
case (value):
(do something)
case (other value):
(do something else)
}
IN your example, you are using a switch syntax that is nothing like that. I
think that your "case " statements are not actually evaluating the value of
$count, but are themselves evaluating to a true value that has nothing to do
with $count.
That `switch` is evaluating to true each case. It's an alternative of using
if-elseif structure.
