我有阵列
`array(
[0] =>array(
[id] => 1,
[item] => ring,
[total] => 1000
),
[1] =>array(
[id] => 1,
[item] => book,
[total] => 1000
),
[2] =>array(
[id] => 1,
[item] => pen,
[total] => 400
)
);`
我需要[id]仅当首先显示相同值时的结果,[total]而其他需要 -如下所示的结果。
`array(
[0] =>array(
[id] => 1,
[item] => ring,
[total] => 1000
),
[1] =>array(
[id] => 1,
[item] => book,
[total] => -
),
[2] =>array(
[id] => 1,
[item] => pen,
[total] => 400
)
);`
谢谢您的帮助。
