$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 '<table width="150px" border="1">';foreach($ary['a'] as $aV){	foreach($ary['b'] as $bV){		foreach($ary['c'] as $cV){			echo "<tr><td>$aV</td><td>$bV</td><td>$cV</td></tr>";		}	}}echo '</table>';

echo '<table width="150px" border="1">';foreach($ary['a'] as $aV){	foreach($ary['b'] as $bV){		foreach($ary['c'] as $cV){			echo "<tr><td>$aV</td><td>$bV</td><td>$cV</td></tr>";		}	}}echo '</table>';


忘了说,  键a,b,c是可能n个的

$ary = array(    'a'=>array('a1','a2'),    'b'=>array('b1','b2'),    'c'=>array('c1','c2'),);echo "<table>\n";echo "<tr><td>a</td><td>b</td><td>c</td></tr>\n";foreach($ary['a'] as $m) {  foreach($ary['b'] as $n) {    foreach($ary['c'] as $v) {      echo "<tr><td>$m</td><td>$n</td><td>$v</td></tr>\n";    }  }}echo "</table>";
[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......);
