php 取出二维数组中不重复的值？
我有一个类似这样的数组：
Array
(
[102] => Array
(
[0] => 36
[1] => 42
[2] => 99
[3] => 186
[4] => 210
[5] => 211
[6] => 213
[7] => 215
[8] => 265
)
[104] => Array
(
[0] => 19
[1] => 42
[2] => 94
[3] => 98
[4] => 106
[5] => 176
[6] => 206
[7] => 210
[8] => 211
[9] => 212
[10] => 213
[11] => 248
[12] => 265
[13] => 271
[14] => 292
)
[105] => Array
(
[0] => 42
[1] => 98
[2] => 206
[3] => 211
[4] => 212
[5] => 213
[6] => 265
)
[106] => Array
(
[0] => 28
[1] => 124
[2] => 127
[3] => 206
[4] => 211
[5] => 212
[6] => 214
)
[111] => Array
(
[0] => 28
[1] => 124
[2] => 127
[3] => 206
[4] => 211
[5] => 212
[6] => 214
)
)
要求:
1、5个大的数组中各取一个值即取出5个值
2、保证取出的5个值各不相同 (5个数组中如果存在相同的数组例如[106] [111] 这两个数组，可以从其中一个取出0（当然可能存在多个个相同的大数组，所以也可以取出多个0） )
最后返回的是键名为 102, 104,105,106,111 ，值为取出非重复值的一维数组

);
// ps: 你给出示例数据时，最好是上面的格式，否则没有人愿意来回答你的问题，
// 因为要把数据格式化成代码可以用的已经很费功夫了，其实我就差点不想回答了
$result = array();
foreach($arr as $k => $v) {
$v = array_diff($v, $result);
$result[$k] = array_shift($v);
}
print_r($result);
