[SOLVED] Array Random

[shamuraq]

Hi guys,

I've a problem with random that i really need help with...

 

Scenario:

$coin = array('0.01'=>'1 cent','0.05'=>'5 cents','0.1'=>'10 cents','0.2'=>'20 cents','0.5'=>'50 cents','1.0'=>'$1');

I now need to randomize the array where i need to store them into into 2 seperate variables to be called out later. Eg if the randomised array is '0.01' and '1 cent',

i need to store it as:

$a = '0.01';

$b = '1 cent';

 

I checked out PHP manual.net and saw this:

$b=array( 'G'=>'Good', 'B'=>'BAD', 'O'=>'OK' );
echo array_rand($b); // 'G' or 'B' or 'O'
echo $b[array_rand($b)]; // 'Good' or 'BAD' or 'OK'

The problem with that is:

if i define $a = array_rand($coin);

i cannot define $b since $b would have to be: $b[array_rand($coin)]

and then it would re randomise the array again...

 

How do i obtain $a and $b from just one array_rand?

Is the key supposed to always correspond to the value? If so couldn't you just store the key only then get the value using that key? If you insist in storing it within 2 values (kinda defeats the purpose of an array). You can do this:

 

$arr = array( 'G'=>'Good', 'B'=>'BAD', 'O'=>'OK' );
$a = array_rand($arr); 
$b = $arr[$a];
