You could also grab the midpoint of the array:

$count = round(count($array), 0);

then populate your new arrays by using a foreach loop:

$x = 0;
foreach($array as $key = $value) {
if ($x =$count) {
$array1[] = $value;
} else {
$array2[] = $value;
}
$x++;
}

Re: Re[2]: [PHP] split array in 2 halfs

[Philip Olson]

You may find this helpful:

  $arr = array('a','b','c','d','e'); 
  $second_half = array_splice($arr,floor(sizeof($arr)/2));
 
  print_r($arr); // Array ( [0] = a [1] = b )
  print_r($second_half); // Array ( [0] = c [1] = d [2] = e )

In the above, $second_half will be one larger then $arr if the number
of elements is odd, otherwise they'll be equally sized halves.  Using
ceil() as opposed to floor() will make $second_half the smaller of the
two.

Philip Olson

Correction:

$count = count($array);
$count = $count/2;
$count = round($count,0);
