[1] => array (7 ){

["Order_id"] => string (3) "117" ["job_id"] => string (2) "51" ["job_name"] => string (24) "trademark registration" ["client_id"] => string (3) "108" ["user_name"] => string (9) "Xiaoming" ["users_id"] => string (1) "5" ["num"] => int (1)

}

I need to merge the same job_name and user_name and add NUM
[1] => array (7 ){

["Order_id"] => string (3) "117" ["job_id"] => string (2) "51" ["job_name"] => string (24) "trademark registration" ["client_id"] => string (3) "108" ["user_name"] => string (9) "Xiaoming" ["users_id"] => string (1) "5" ["num"] => int (1)

Your algorithm is simple and you can write it yourself!

For more information, see the following.

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