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

回复讨论(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', 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;}

foreach(array_chunk(array_keys($array), 6) as $v){     $len = count($v);	 if($len \n";	 echo "".implode("\n",$v)."\n";	 echo "\n";	 	 $vl = array_map('strtolower', $v);	 echo "\n";	 echo "".implode("\n",$vl)."\n";	 echo "\n";	 }

感谢几位大神的回复 小弟收益匪浅, jordan102 版主可能没理解这个问题的本质其实是想隔行显示标题和内容 ,而不是把大写转为小写的问题 ,可能是我给的数组误导了你,不过如果针对我给数组,你的思路也很值得学习, 再次感谢几位

楼主新人啊！加油！过来凑个热闹！

php 有丰富的数组函数，这里再提供一种写法

$array = array ('A' => 'a', 'B' => 'b', 'C' => 'c', 'D' => 'd', 'E' => 'e', 'F' => 'f', 'G' => 'g', 'H' => 'h', 'I' => 'i', 'J' => 'j', 'K' => 'k', 'L' => 'l', 'M' => 'm', 'N' => 'n', 'O' => 'o', 'P' => 'p', 'Q' => 'q', 'R' => 'r', 'S' => 's', 'T' => 't', 'U' => 'u', 'V' => 'v', 'W' => 'w', 'X' => 'x', 'Y' => 'y', 'Z' => 'z' );$a = array_map(null, array_chunk(array_keys($array), 6), array_chunk($array, 6));foreach($a as $rs)  foreach($rs as $r) {    echo "\n";    if(count($r) $v\n";    echo "\n";  }

一层循环便可。

$arr = array ('A' => 'a', 'B' => 'b', 'C' => 'c', 'D' => 'd', 'E' => 'e', 'F' => 'f', 'G' => 'g', 'H' => 'h', 'I' => 'i', 'J' => 'j', 'K' => 'k', 'L' => 'l', 'M' => 'm', 'N' => 'n', 'O' => 'o', 'P' => 'p', 'Q' => 'q', 'R' => 'r', 'S' => 's', 'T' => 't', 'U' => 'u', 'V' => 'v', 'W' => 'w', 'X' => 'x', 'Y' => 'y', 'Z' => 'z' );$page = (int)((count($arr)-1)/6)+1;echo '

';for($i=0; $i'; echo ''; echo ''; echo ''; echo ''; echo '';}echo '

'.implode('	',array_pad(array_keys(array_slice($arr, $i*6, 6)),6,'')).'
'.implode('	',array_pad(array_slice($arr, $i*6, 6),6,'')).'

';
