validation three values

[kirk112]

Hi

 

I have following variables;

 

$v1 = 1

$v2 = 1

$v3 = 2

 

is there an easy way of checking to make sure that none of the variables have the same values I know how to do it using multiple if statements just wondering if there is a shorter way of doing it

 

Thanks.

If you were to use an array, you could do this:

 

<?php
$v[1] = 1;
$v[2] = 1;
$v[3] = 2;
if(count($v) != count(array_unique($v))){
    echo 'duplicates!';
}else{
    echo 'fine';
}
?>
