A simple example of using foreach() in PHP to traverse a two-dimensional array, foreach two-dimensional array

The first type

Want to use foreach() to traverse the entire two-dimensional array:

$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.''; 

The output result is:

0=>linux server configuration and management
1=>Array

Of course, I actually want all the specific content, not the output array. . .

So you should adopt the following approach and add a judgment statement:

$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.''; 

then the output is:

0=>linux server configuration and management
lk
ok

echo "<br>"; 
echo "<h1 id="php遍历二维数组">php遍历二维数组</h1>"; 
//$team = array('lk','ok'); 
//$book = array('linux服务器配置与管理',$team); 
$arr = array( 
array('name'=>'系统配置','url'=>'&#63;action=config&do=config'), 
array('name'=>'验证码配置','url'=>'&#63;action=config&do=seccode'), 
array('name'=>'模板管理','url'=>'&#63;action=config&do=tpl'), 
array('name'=>'帐号管理','url'=>'&#63;action=admin&do=list'), 
array('name'=>'添加帐号','url'=>'&#63;action=admin&do=add')); 
foreach($arr as $k=>$val){ 
  echo "name:".$val["name"]."/n"; 
}
