Random Greeting in PHP

I was searching for a php  list of greetings but couldn’t find one so I made my own. Thought this may be helpful to someone else looking for a list. Here is how to show a random greeting in php. Much like the flickr welcome page.

//random array function you can use or write your own
function randomArrayVar($array)
{
if (!is_array($array)){
return $array;
}
return $array[array_rand($array)];
}

//list of grettings as arary

$greeting= array(
             "aloha"=>"Aloha",
             "ahoy"=>"Ahoy",
             "bonjour"=>"Bonjour",
             "gday"=>"G'day",
             "hello"=>"Hello",
             "hey"=>"Hey",
             "hi"=>"Hi",
             "hola"=>"Hola",
             "howdy"=>"Howdy",
             "rawr"=>"Rawr",
             "salutations"=>"Salutations",
             "sup"=>"Sup",
             "whatsup"=>"What's up",
             "yo"=>"Yo");

//echo greeting
echo (randomArrayVar($greeting));
