例如: 如下数组需去重并合并相同的数据
//by www.qzphp.cn
{
"code": 200,
"data": [
{
"title": "客房服务",
"id": 4,
"count": 1
},
{
"title": "设备报修",
"id": 5,
"count": 1
},
{
"title": "客房服务",
"id": 4,
"count": 1
}
],
"msg": "查询成功"
}可以采用如下代码进行操作:
//by www.qzphp.cn
$data = array(3) {
[0] => array(3) {
["title"] => string(12) "客房服务"
["id"] => int(4)
["count"] => int(1)
}
[1] => array(3) {
["title"] => string(12) "设备报修"
["id"] => int(5)
["count"] => int(1)
}
[2] => &array(3) {
["title"] => string(12) "客房服务"
["id"] => int(4)
["count"] => int(1)
}
}
$result = array();
foreach($data as $val){
$key = $val['id'].'_'.$val['title'];
if(!isset($result[$key])){
$result[$key] = $val;
}else{
$result[$key]['count'] += $val['count'];
}
}
$result = array_values($result);结果如下：
//by www.qzphp.cn
{
"code": 200,
"data": [
{
"title": "客房服务",
"id": 4,
"count": 2
},
{
"title": "设备报修",
"id": 5,
"count": 1
}
],
"msg": "查询成功"
}
