一个关于数组循环的问题
现有一数组如下

$array = array ('A' => 'a', 'B' => 'b', 'C' => 'c', 'D' => 'd', 'E' => 'e', 'F' => 'f', 'G' => 'g', 'H' => 'h', 'I' => 'i', 'J' => 'j', 'K' => 'k', 'L' => 'l', 'M' => 'm', 'N' => 'n', 'O' => 'o', 'P' => 'p', 'Q' => 'q', 'R' => 'r', 'S' => 's', 'T' => 't', 'U' => 'u', 'V' => 'v', 'W' => 'w', 'X' => 'x', 'Y' => 'y', 'Z' => 'z' );

需要循环数组实现以下效果

A	B	C	D	E	F
a	b	c	d	e	f
G	H	I	J	K	L
g	h	i	j	k	l
M	N	O	P	Q	R
m	n	o	p	q	r
S	T	U	V	W	X
s	t	u	v	w	x
Y	Z
y	z

请问各位该如何实现呢
------解决方案--------------------

$array = array ('A' => 'a', 'B' => 'b', 'C' => 'c', 'D' => 'd', 'E' => 'e', 'F' => 'f', 'G' => 'g', 'H' => 'h', 'I' => 'i', 'J' => 'j', 'K' => 'k', 'L' => 'l', 'M' => 'm', 'N' => 'n', 'O' => 'o', 'P' => 'p', 'Q' => 'q', 'R' => 'r', 'S' => 's', 'T' => 't', 'U' => 'u', 'V' => 'v', 'W' => 'w', 'X' => 'x', 'Y' => 'y', 'Z' => 'z' );

for($i=0; $i  echo '', PHP_EOL;
  $t1 = array_keys(array_slice($array, $i, 6)) + array_fill(0, 6, '');
  $t2 = array_values(array_slice($array, $i, 6)) + array_fill(0, 6, '');
  foreach($t1 as $v) {
    echo "  $v", PHP_EOL;
  }
  echo '', PHP_EOL;

  echo '', PHP_EOL;
  foreach($t2 as $v) {
    echo "  $v", PHP_EOL;
  }
  echo '', PHP_EOL;
}
