array_key_exists() 可以查找2维数组的 键名吗
array
(
1 => '1234',
3 => 'ssssaaaa',
'ssssaaaa' => array ( 19 => 'sssssss', ),
4 => '11111',
5 => '222222',
6 => '33333',
7 => '111111',
8 => '1233455',
9 => '321',
10 => '123',
11 => '111',
12 => '12345',
13 => '1234',
14 => '1234',
20 => 'lirui',
'lirui' => array ( 23 => 'ssss', 22 => '432132', 21 => '1234', ),
)
比如上面2个2维的数组， lirui，ssssaaaa
------解决方案--------------------
看名称都知道 这个函数是返回KEY存不存在 查找一个数组的所有键名 用 print_r(array_keys($arr['lirui']));
