array=['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r'];
console.log(array.slice(0,3));
console.log(array.slice(3,6));
console.log(array.slice(6,9));
console.log(array.slice(9,12));
The above outputs:
["a", "b", "c"]
["d", "e", "f"]
["g", "h", "i"]
["j", "k", "l"]
Same output with PHP:
$input = array('a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r');
print_r(array_slice($input,0,3));
print_r(array_slice($input,3,3));
print_r(array_slice($input,6,3));
print_r(array_slice($input,9,3));
//output

Misc stuff,
js:

console.log(array.slice(a,b));//items
js:printing links. TESTED OK!
