如何使用foreach()遍历二维数组和多维数组

$team = array('lk','ok');
$book = array('linux服务器配置与管理',$team);
 
foreach($book as $k=>$val) //for $book each $value( as )
echo $k.'=>'.$val.'';

$team = array('lk','ok');
$book = array('linux服务器配置与管理',$team);
 
foreach($book as $k=>$val) //意思是for $book each $value( as )
if( is_array($val) ) foreach( $val as $value) echo $value.'';
else echo $k.'=>'.$val.'';

echo "<br>";
echo "<h1>php遍历二维数组</h1>";
//$team = array('lk','ok');
//$book = array('linux服务器配置与管理',$team);
$arr = array(
array('name'=>'系统配置','url'=>'?action=config&do=config'),
array('name'=>'验证码配置','url'=>'?action=config&do=seccode'),
array('name'=>'模板管理','url'=>'?action=config&do=tpl'),
array('name'=>'帐号管理','url'=>'?action=admin&do=list'),
array('name'=>'添加帐号','url'=>'?action=admin&do=add'));
foreach($arr as $k=>$val){
  echo "name:".$val["name"]."/n";
}

<?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>"; 
}
