请教二维数组矩阵算法
<br />$ary = array(<br /> 'a'=>array('a1','a2'),<br /> 'b'=>array('b1','b2'),<br /> 'c'=>array('c1','c2'),<br />);<br />登入後複製
如何把上面的数组，输出到页面成这样啊
------解决方案--------------------<br /><br />echo '<table width="150px" border="1">';<br />foreach($ary['a'] as $aV){<br /> foreach($ary['b'] as $bV){<br /> foreach($ary['c'] as $cV){<br /> echo "<tr><td>$aV</td><td>$bV</td><td>$cV</td></tr>";<br /> }<br /> }<br />}<br />echo '</table>';<br /><br />登入後複製
