random number

[shakeelstha]

I have an array of numbers. I need to get the random number (random index) from the array. The

 

number picked before should not be picked the next time. How can I do that.

<?php
$bag = array(1,2,3,4,5);

shuffle ($bag);                   // shake the bag

for ($i=0; $i<5; $i++)
{
    echo array_pop($bag);          // pull from the bag
}
?>
