我有一个如下的数组,我想在一个单独的数组中获取 'id' 前面的所有值。比如:arry('12', '10', '11', '9')
array
3 =>
array
'occurance' => int 4
'id' => string '12' (length=2)
1 =>
array
'occurance' => int 3
'id' => string '10' (length=2)
2 =>
array
'occurance' => int 2
'id' => string '11' (length=2)
0 =>
array
'occurance' => int 1
'id' => string '9' (length=1)
