Question

I have the following array:

$array = array(1,0,0,0,1,1,1,1,0,1,1,1,1,0,1,1,0,1,0,0,1,0,1);

I want split it up into individual arrays so that each array contains seven or less values.

So for example the first array will become:

$one = array(1,0,0,0,1,1,1)
$two = array(1,0,1,1,1,1,0)
$three = array(1,1,0,1,0,0,1);
$four = array(0,1);

Also how would you count the number of times 1 occurs in array one?

Answer 1

array_chunk() is what you are looking for.

 $splitted = array_chunk($array, 7);

For counting the occurences I would be lazy. If your arrays only contain 1s or 0s, then a simple array_sum() would do:

 print array_sum($splitted[0]);    // for the first chunk
