Description:
------------
Would like to see a function for comparing strings. is_unique() seems to be open.

Ability to compare more than 2 strings for uniqueness, if they are not unique false is returned, else true.

$choice1 = "yes";
$choice2 = "no";
$choice3 = "maybe";
$choice4 = "no";

if(is_unique($choice1,$choice2,$choice3,$choice4)){
   echo "yes";
}else{
   echo "no";
}

Indeed ... a userland solution is easy enough to write.

Considering the age of this request and the rather few votes in
favor, there obviously is not a widespread need for this
functionality, which can easily be implemented in userland anyway.
So I'm closing as won't fix.
