Question

I have an array which I want to slice in 4 other arrays because I want to display the content of the first array on four columns.

I have tried the code above, but what I get is N columns with 4 items.

$groups = array();
for ($i = 0; $i < count($menu); $i += 4) $groups[] = array_slice($menu, $i, 4);

Can this be modified in order to get exactly 4 columns and distribute the values so they fit?

Answer 1

Like Michael Berkowski suggested:

$groups = array_chunk($menu,4);

Should give you what you need. If you’re more into “manual labour”:

$groups = array();
while($groups[] = array_splice($menu,0,4))
{//no need for any code here ^^ chunks the array just fine
    printf('This loop will run another %d times<br/>',(int)ceil(count($menu)/4));
}

Update:

I see I got this a bit wrong… want to chunk into 4 arrays, not into arrays of four:

$groups = array_chunk($menu,(int)ceil(count($menu)/4));
