[SOLVED] array stuff

[kellz]

*looks weirdly at the subject*

anyhoo.. so I've been reading about arrays (i already know the basics) and I want to do something totally kewl but im not sure how.. anyway here is the array type that im trying to figure out:

 

$myClass = array(
               'jason' => 'retard',
               'shane' => 'cute',
               'emma' => 'bestest friend ever!',
               'sara' => 'back stabbing b*tch!',
               'ricky => 'genius',
               'sean' => 'lovely boyfriend',
               'tim' => 'funny person',
               'tanya' => 'eats to much',
               'elin' => 'doesn't eat enough',
               'martyn' => 'SEXYYYYYYYY',
               'neil' => 'smokes....(not just cigarettes!)',
               'Gary' => 'need's to wash more often (smelly)',
               'Anna' => 'I don't know her so i assume she's evil',
               'Sophie' => 'Paarrrtyyy!!! <3 <3',
               'Mark' => 'stop fighting in school',
               'Hannah' => 'bring it on b*tch!',
               'Amy' => 'owed me £5 for over a year lol',
               'Charlotte' => 'I am not a geek I am a nerd! and your ugly so shutup.'
);

 

ok so thats most of my class (in real life ofcourse) and i want to know how i can choose a random person in that array and then print his/her name and the description of that person.

 

I know how to get the description but i dont know how to get the names? (keys?)

 

thanks

I'm afraid you can't randomly select a number an use it to reference the array, if the array is associative.  What you would have to do is pick a random number and then loop through the array that many times until you reach the desired key.  For example:

 

$random = rand(0, count($myClass)-1);  //picks a number between 0 and the number of elements in your array
$selected_key = "";
for ($i = 0; $i < $random; $i++)
next($myClass);

//the array pointer is pointing at the selected value
$key = key($myClass);
$value = current($myClass);
