Hey guys, I need some help with this problem, I am trying to develop a function that generates and returns 'n' sets of random lottery numbers as a 2 dimensional array. I also need to make use of another function I had created earlier on(below too). The code I have at the minute feels like its nearly there but i am struggling to finish it off, can anyone help me out so I can finish it off?

getRow function:
function getRow()
{
    $ball = [];
    for($i=1;$i<=6;$i++){
        $ball[] = rand(1,59);
    }
    sort($ball);
    return $ball;
}

echo '<pre>';
print_r(getRow());
echo '</pre>';


getSet 2 dimensional array:
function getSet($n)
{
$n = array('rows'=>array(
                           getRow($ball)
                           ),
           'sets'=>array(
                           getSet($ball)
                           )
);
return $ball;
  echo "<pre>look\n".
        print_r(getSet(5));
        '</pre>';
}
echo '<pre>';

First off I don't really know what you are trying to do,
but I think your problem is you are trying to push a number to the array, but you are doing it wrong.
Is this what you are trying to do?

with comments:

function getRow()
{
    $ball = []; // clear the array & btw this line might not be needed
    for($i=1;$i<=6;$i++){
        $ball[$i] = rand(1,59);
    }
    // $ball = 6 random numbers
    $ball = sort($ball);  // put them in numerical order?
    return $ball; // return an array of six random numbers
}

echo '<pre>';
print_r(getRow());
echo '</pre>';



drier code:

function getRow()
{
    for($i=1;$i<=6;$i++){
        $ball[$i] = rand(1,59);
    }
    return sort($ball);
}

Thanks for the reply, however I already done this part. This is the question I am trying to answer:

Develop a function getSet($n) that generates and returns n sets of random lottery ball numbers as a 2-dimensional array. Your solution to this task should make use of the getRow() function developed it task 2 to generate the rows in your 2-dimensional array. Again test the solution by making a call to the print_r(getSet(5)).

function getSet($numberOfSets){
    for ($i=0; $i<$numberOfSets; $i++) {
        $sets[$i] = getRow();
    }
    return $sets;
}

/*
getSet(3) would return something like this
[
    [23, 56, 43, 1, 2, 32],
    [58, 57, 45, 45, 21, 5],
    [12, 10, 11, 8, 9, 16]
]
*/
$mysets = getSet(3);
$mysets[0] // returns [23, 56, 43, 1, 2, 32]
$mysets[0][4] // returns 2
