如何去除一些数据(数组)
array (
'cid' => '9',
'pid' => '1',
),
2 =>
array (
'cid' => '8',
'pid' => '1',
),
3 =>
array (
'cid' => '6',
'pid' => '1',
),
4 =>
array (
'cid' => '4',
'pid' => '1',
),
5 =>
array (
'cid' => '11',
'pid' => '1',
),
),
2 =>
array (
0 =>
array (
'cid' => '7',
'pid' => '2',
),
),
3 =>
array (
0 =>
array (
'cid' => '5',
'pid' => '3',
),
),
)
大家看这个数组，我用下面的方法，将cid号取出来。
得到结果为
array (
0 => '1',
1 => '2',
2 => '3',
3 => '10',
4 => '9',
5 => '8',
6 => '6',
7 => '4',
8 => '11',
9 => '7',
10 => '5',
)
这是取出所有的cid号，不过我不想要pid=0的数据，也就是说如何只取出pid！=0的cid号，谢谢！！
