一個關於數組迴圈的有關問題

一個關於數組迴圈的問題
現有一數組如下

$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' );

需要迴圈數組實現以下效果

 

  

   

    
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
    

    

    

    

   
  
 

請問各位該如何?呢
------解決方案--------------------

$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;
