array(2) {
[0] => array(11) {
[0] => array(1) {
["cid"] => string(4) "1"
}
[1] => array(1) {
["cid"] => string(4) "1"
}
[2] => array(1) {
["cid"] => string(3) "2"
}
[3] => array(1) {
["cid"] => string(4) "3"
}
}
[1] => array(13) {
[0] => array(1) {
["cid"] => string(4) "1"
}
[1] => array(1) {
["cid"] => string(4) "2"
}
[2] => array(1) {
["cid"] => string(4) "2"
}
[3] => array(1) {
["cid"] => string(4) "4"
}
[4] => array(1) {
["cid"] => string(4) "4"
}
}
}
这样一个数组 我怎么把去重啊！去重后应该是这样的
array(2) {
[0] => array(13) {
["0"] => string(4) "1"
["1"] => string(3) "2"
["2"] => string(4) "3"
｝
[1] => array(13) {
["0"] => string(4) "1"
["1"] => string(4) "2"
["3"] => string(4) "4"
}
}
