PHP Array re-arrange to Multi Dimensional -


i have array structure , wanted re-arrange 1 below. suggestions faster/simple fix? did addition of dates. thanks! :)

input:

array (     [0] => array         (             [user_id] => 255             [display_name] => mark             [company_name] => company_a         )     [1] => array         (             [user_id] => 150             [display_name] => paul             [company_name] => company_a         )     [2] => array         (             [user_id] => 25             [display_name] => hulk             [company_name] => company_b         )     [3] => array         (             [user_id] => 50             [display_name] => bob             [company_name] => company_b         ) )

output:

array (     [company_a] => array         (             [company_total_hours] => 20h 45m             [employees] => array                 (                     [0] => array                         (                             [user_id] => 255                             [display_name] => mark                         )                     [1] => array                         (                             [user_id] => 150                             [display_name] => paul                         )                 )         )     [company_b] => array         (             [company_total_hours] => 7h 30m             [employees] => array                 (                     [0] => array                         (                             [user_id] => 25                             [display_name] => hulk                         )                     [1] => array                         (                             [user_id] => 50                             [display_name] => bob                         )                 )         ) )

my attempts:

<?php $company_names = array(); foreach ($records $k => $v) {     $company_names[] = $v->company_name; } $company_names = array_unique($company_names);  // hard coded testing if (count($company_names) > 0) {     foreach($company_names $k2 => $v2) {         $final_array[$v2]['company_total_hours'] = rand(1, 20);          $final_array[$v2]['employees'] = array(             array('user_id' => '255', 'display_name' => 'mark'),             array('user_id' => '150', 'display_name' => 'paul')         );     } }  // on-going testing right here....

i don't see derive hours left out.

$i = 0; foreach($vals $keys => $arrays) {         if(!isset($new[$arrays['company_name']]))             $i = 0;         $new[$arrays['company_name']]['employees'][$i]['display_name']  =   $arrays['display_name'];         $new[$arrays['company_name']]['employees'][$i]['user_id']       =   $arrays['user_id'];         $i++;     }

gives you:

array (     [company_a] => array         (             [employees] => array                 (                     [0] => array                         (                             [display_name] => mark                             [user_id] => 255                         )                      [1] => array                         (                             [display_name] => paul                             [user_id] => 150                         )                  )          )      [company_b] => array         (             [employees] => array                 (                     [0] => array                         (                             [display_name] => hulk                             [user_id] => 25                         )                      [1] => array                         (                             [display_name] => bob                             [user_id] => 50                         )                  )          )  )

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver.
