Checking a variable against a number of values

[AbydosGater]

Hi
I was editing my site the oder day and i came up with an idea,
but i need to be able to check a variable against a number of values...
as in

[code]
if ($myvar != ***here I want to have a number of things that it might not be***)
    {
$myvar = "defaultvars";
    }
[/code]

so if my variable is not equal to a number of values, it is changed to the default one, like "index"

How would i do this for the bit
($myvar != how would i list my values here?

Thank you

Take a look at the [a href=\"http://ca.php.net/manual/en/function.in-array.php\" target=\"_blank\"]in_array function[/a] - that should do it for you.

I find this very confusing,
Would there be any other way?

There are lots of other ways.

in_array is probably the easiest, especially if you have more than 3 or 4 values that you are wanting to compare.

Alternatives include using a very long if statement:

if ($value == '1' || $value == '2' || $value == '3' etc...) {

or using a switch statement:

The switch woulnt work because i want to check the variable against about 5 values,
and if it does not match any of the values, i want to assign it the value "index",
So if someone for example types in "pizza", i want it to change the variable to index, so there are no errors!

But i think this will work...
[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]
if ($value == '1' || $value == '2' || $value == '3' etc...) {
[/quote]

so what would i do,

[code]if ($myvar != 'value1' || $myvar != '2' || and so on?[/code]
Would that be right?

Thats what i was going to do in the first place, But i didnt know what to put in between all the values,
i was going to use "&&" instead of "||",
But will the above work?
so in total it would be like



[code]
if ($myvar != 'value1' || $myvar != 'value2' || $myvar != 'value3' || $myvar != 'value4'
    {
    $myvar = "index"
     }
[/code]
