请教二维数组矩阵算法

$ary = array(	'a'=>array('a1','a2'),	'b'=>array('b1','b2'),	'c'=>array('c1','c2'),);

如何把上面的数组，输出到页面成这样啊

回复讨论(解决方案)

echo '

';foreach($ary['a'] as $aV){ foreach($ary['b'] as $bV){ foreach($ary['c'] as $cV){ echo ""; } }}echo '

$aV

$bV

$cV

';

echo '

';foreach($ary['a'] as $aV){ foreach($ary['b'] as $bV){ foreach($ary['c'] as $cV){ echo ""; } }}echo '

$aV

$bV

$cV

';
忘了说， 键a,b,c是可能n个的

$ary = array(    'a'=>array('a1','a2'),    'b'=>array('b1','b2'),    'c'=>array('c1','c2'),);echo "

\n";echo "\n";foreach($ary['a'] as $m) { foreach($ary['b'] as $n) { foreach($ary['c'] as $v) { echo "\n"; } }}echo "

a	b	c
$m	$n	$v

";[code=html]

a	b	c
a1	b1	c1
a1	b1	c2
a1	b2	c1
a1	b2	c2
a2	b1	c1
a2	b1	c2
a2	b2	c1
a2	b2	c2

忘了说， 键a,b,c是可能n个的，如:a,b,c,d,e,f...................

$ary = array(    'a'=>array('a1','a2'),    'b'=>array('b1','b2'),    'c'=>array('c1','c2'),	'd'=>array('d1','d2'),	'e'=>array('e1','e2'),	//..........多行......);
