PHP :1D array to 2D array

Question

Hi I have a 1D array (1 by 20) that I would like to transform to a 2D Array (4 by 5)

$winning_number  = 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

to

1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
16 17 18 19 20

right now I am using this code:

foreach ($wining_no as $boulex)
{

    for($i=0;$i<$5;$i++)
    {
        if($i==0)
        {
            for($j=0;$j<$4;$j++)
            {   
                $boule_array[$j][$i] = $boulex;
            }
        }
    }
}

For some reason this does not work

Maybe the problem is the typo: $4; inside of the third loop, in the condition. $j=0;$j<$4;$j++. Because I think you mean the integer 4. — Crisoforo Gaspar

You could use the array_chunk($array, $size) function For you it would be like this

array_chunk($winning_number, 5);
