Multiple PHP array split -

array (a1, a2, a3, a4, a5, a6, a7, a8, a9, a10, a11, a12); array (b1, b2, b3, b4, b5, b6, b7, b8, b9, b10, b11, b12); array (c1, c2, c3, c4, c5, c6, c7, c8, c9, c10, c11, c12);

from upper array want this:

array (a1, a2, a3, a4); array (b1, b2, b3, b4); array (c1, c2, c3, c4); array (a5, a6, a7, a8); array (b5, b6, b7, b8); array (c5, c6, c7, c8); array (a9, a10, a11, a12); array (b9, b10, b11, b12); array (c9, c10, c11, c12); //etc.

i have opportunities columns check. 4-columns above or 3.

the list long.

$input_array = array ("a1", "a2", "a3", "a4", "a5", "a6", "a7", "a8", "a9", "a10", "a11", "a12"); var_dump(array_chunk($input_array, 4, true));

out set :

array (size=3) 0 => array (size=4) 0 => string 'a1' (length=2) 1 => string 'a2' (length=2) 2 => string 'a3' (length=2) 3 => string 'a4' (length=2) 1 => array (size=4) 0 => string 'a5' (length=2) 1 => string 'a6' (length=2) 2 => string 'a7' (length=2) 3 => string 'a8' (length=2) 2 => array (size=4) 0 => string 'a9' (length=2) 1 => string 'a10' (length=3) 2 => string 'a11' (length=3) 3 => string 'a12' (length=3)
