的例子
$arr = array('aa' => array('bb' => array('id'=>5,'grade'=>5),
'cc' => array("name"=>'some'),
'dd' => array('ctime'=>1001)),
'ee' => array('ff' =>array('age'=> 25,'sex'=>1)));
function a($arr){
if(!is_array($arr)){
echo $arr."\n";
}else
foreach($arr as $k=>$v){
if(is_array($v)){
echo "键是$k"."\n";
echo a($v)."\n";
}else{
echo "键是$k"."\n";
echo $v."\n";
}
}
}
a($arr);
结果
键是aa
键是bb
键是id
5
键是grade
5
键是cc
键是name
some
键是dd
键是ctime
1001
键是ee
键是ff
键是age
25
键是sex
1
