我有這樣一個陣列
[1] => array(7) {

<code>["order_id"] => string(3) "117"
["job_id"] => string(2) "51"
["job_name"] => string(24) "商标注册"
["client_id"] => string(3) "108"
["user_name"] => string(9) "小明"
["users_id"] => string(1) "5"
["num"] => int(1)</code>

}
[2] => array(7) {

<code>["order_id"] => string(3) "118"
["job_id"] => string(1) "2"
["job_name"] => string(18) "外资公司注册"
["client_id"] => string(3) "103"
["user_name"] => string(10) "小红 "
["users_id"] => string(1) "2"
["num"] => int(1)</code>

}
[3] => array(7) {

<code>["order_id"] => string(3) "119"
["job_id"] => string(1) "2"
["job_name"] => string(18) "外资公司注册"
["client_id"] => string(3) "109"
["user_name"] => string(10) "小红 "
["users_id"] => string(1) "2"
["num"] => int(1)</code>

}

我需要將job_name跟user_name相同的合併並將NUM相加變成
[1] => array(7) {

<code>["order_id"] => string(3) "117"
["job_id"] => string(2) "51"
["job_name"] => string(24) "商标注册"
["client_id"] => string(3) "108"
["user_name"] => string(9) "小明"

求大神們指導指導感激不盡

你這個演算法簡單，你自己可以寫出來的！

參考如下，你自己在用著改改

<code>$newArray = [];
foreach($array as $key=>$val){
    foreach($array as $k=>$v){
        if($val['job_name'] == $v['job_name'] && $val['user_name'] == $v['user_name']){
            $newArray = $val;
            $newArray['num'] = $val['num']+$v['num'];
        }
    }
}</code>
