PHP中多维数组的foreach遍历示例

<?php 
//声明一个三维数组 
$info=array( 
"user"=>array( 
array(1,"zhangsan",20,"nan"), 
array(2,"lisi",20,"nan"), 
array(3,"wangwu",25,"nv") 
), 
"score"=>array( 
array(1,100,98,95,96), 
array(2,56,98,87,84), 
array(3,68,75,84,79) 
), 
"connect"=>array( 
array(1,'2468246',"salkh@bbs.com"), 
array(2,'343681643',"aikdki@sina.com"), 
array(3,'3618468',"42816@qq.com") 
) 
); 
//循环遍历，输出一个表格 
foreach($info as $tableName=>$table){ 
echo "<table align='center' border='1' width=300>"; 
echo "<caption><h1>".$tableName."</h1></caption>";//以每个数组的键值作为表名 
foreach($table as $row){ 
echo "<tr>"; 
foreach($row as $col){ 
echo "<td>".$col."</td>"; 
} 
echo "</tr>"; 
} 
echo "</table>"; 
} 
?>
