PHP數組合并重組問題

我有這樣一個數組
[1] => array(7) {

["order_id"] => string(3) "117"["job_id"] => string(2) "51"["job_name"] => string(24) "商標註冊"["client_id"] => string(3) "108"["user_name"] => string(9) "小明"["users_id"] => string(1) "5"["num"] => int(1)

}
[2] => array(7) {

["order_id"] => string(3) "118"["job_id"] => string(1) "2"["job_name"] => string(18) "外資公司註冊"["client_id"] => string(3) "103"["user_name"] => string(10) "小紅 "["users_id"] => string(1) "2"["num"] => int(1)

}
[3] => array(7) {

["order_id"] => string(3) "119"["job_id"] => string(1) "2"["job_name"] => string(18) "外資公司註冊"["client_id"] => string(3) "109"["user_name"] => string(10) "小紅 "["users_id"] => string(1) "2"["num"] => int(1)

}

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

["order_id"] => string(3) "117"["job_id"] => string(2) "51"["job_name"] => string(24) "商標註冊"["client_id"] => string(3) "108"["user_name"] => string(9) "小明"["users_id"] => string(1) "5"["num"] => int(1)

}
[2] => array(7) {

["order_id"] => string(3) "118"["job_id"] => string(1) "2"["job_name"] => string(18) "外資公司註冊"["client_id"] => string(3) "103"["user_name"] => string(10) "小紅 "["users_id"] => string(1) "2"["num"] => int(2)

}

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

$newArray = [];foreach($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'];        }    }}
