Random array

PHP
1

How do I output the numbers, 1-11 in a random order like 5, 7, 4, 11, 2, 3, 1, 9, 6, 8, 10

2

populate an array, call shuffle on it, loop over it and output each item

No offense intended Luke, but IMHO PHP has a fairly well documented manual http://www.php.net/manual/en/function.rand.php
Is there something that fails to do for your needs?

I’m trying to figure out the answer to this sample question…

  1.  In PHP, create a randomized array with values 1-11, where the first three elements are grouped together.

Example Output: 5, 7, 4, 11, 2, 3, 1, 9, 6, 8, 10

I know how to generate a random number from 1 to 11 (rand(1,11)) and dont even know where to start (the question doesnt even seem like something like that is doable) Can you give me a point in the right direction?

What do you mean by “grouped together”, an array or cocatenated?

7 
$startArray = range(1, 11); // create an array containing the values 1 through 11
shuffle($startArray); // shuffle them so they are in a random order
echo join(', ', $startArray); // output them to the screen

I lloks like after the array is shuffled, the first three elements (1, 2, 3) are grouped together in the array?
Is this ok?


$startArray = range(1, 11);
shuffle($startArray);
//how do I group the first three elements in the array?, array_chunk
echo join(', ', $startArray);

Give me an example of your expected output.

Are you expecting to just see the first 3 random numbers?
