Anything wrong with this switch?

[ChilliBoy]

Hi,

I was just wondering if there was anything wrong with this switch statment - as it doesn't seem to be working:
switch ($Folder[2])
{
case $Folder[2] != "index.php":
$Text = $TextDPurple;
break;
}

What I'm aiming to do is :- if Folder[2] is not index.php then text is TextDPurple.

However, when viewed, TextDPurple is not being incorporated within any of the files - therefore the script must be wrong.

Is there a better way of writing this "switch".

Sure, like this:

  if ($Folder[2] != "index.php") {
    $Text = $TextDPurple;
  }

I don't think the switch statement can handle negated equalities like that...I think it's just for comparing values. I use if/else statements for anything that requires less than 3 possible outcomes, for the most part.

If you are set on a switch statement you could use this, but the if statement is shorter.

switch ($Folder[2])
{
case "index.php";
$Text = "insert whatever you want it to be when not index.php";
break;

default;
$Text = $TextDPurple;
break;
}

Hi,

Thanks for the help - think I'll go for the switch statement, as it is one part of one huge switch statement.

Are you sure that switch can't handle 'negated'? I don't understand why it shouldn't as you can use most boolean operators eg:

{
case $Folder[2] > 4:
$Text = $TextDPurple;
break;
case $Folder[2] <= 4:
$Text = $TextBlue;
break;
}

It seems very strange if it does not handle ! when the above is ok. Could someone clarify this.

TWTCommish - Just my general thoughts :- I tend to do the opposite, us switch for a greater number of possible outcomes (use a switch within a switch etc etc) - I think it makes code a little easier to read, but essentially no difference.

I'm not sure why, but obviously it doesn't work. My big red book says that PHP's switch statement is much more flexible than other languages, so maybe they only added a few little functionalities to it.

Heck, I dunno. I use Selects if I need to alter the value of the variable with more than three possible outcomes, but that's about it.
