How to store all data with same key together - php

Question

I have an array which looks like this:
Array
(
[companyid] => 22
[userid] => Array
(
[0] => 60
[1] => 61
[2] => 65
[3] => 63
[4] => 64
[5] => 66
[6] => 68
[7] => 69
[8] => 70
[9] => 71
)
[username] => Array
(
[0] => nu1234
[1] => nu12345
[2] => username1235
[3] => testtttttt
[4] => username123
[5] => nu123
[6] => nu
[7] => sdgsdgsdg
[8] => testtttttt1234
[9] => nu1235678910
[10] =>
)
[password] => Array
(
[0] =>
[1] =>
[2] =>
[3] =>
[4] =>
[5] =>
[6] =>
[7] =>
[8] =>
[9] =>
[10] =>
)
)
How can I merge the same keys together, and for all of them add the first value which in this case is 22?
Needed end result:
Array
(
[0] => Array
(
[companyid] => 22
[userid] => 35
[username] => dfhdfhdf
[password] => dfhdfhdfhdf
)
[1] => Array
(
[companyid] => 22
[userid] => 35
[username] => dfhdfhdf
[password] => dfhdfhdfhdf
)
[2] => Array
(
[companyid] => 22
[userid] => 35
[username] => dfhdfhdf
[password] => dfhdfhdfhdf
)
)
I've tried multiple things but nothing gives me the desired result.
Before when I had only two values I did this:
foreach($useroutput['username'] as $key => $val){
if(!empty($val)){
$users[] = array_combine(['username','password'],array_column($useroutput, $key));
}
}
But I cannot get it to work for more than 2 values. The array just shows empty when I print it.
I've also tried multiple combinations of the code below:
foreach($useroutput as $key => $val){
$newarray[$key][]['companyid'] = $useroutput['companyid'];
$newarray[$key][]['userid'] = $useroutput['userid'];
$newarray[$key][]['username'] = $useroutput['username'];
$newarray[$key][]['password'] = $useroutput['password'];
}
array_merge also didn't do what I need.

Answer 1

$new_array = [];
foreach ($useroutput['userid'] as $key => $val) {
$new_array[] = [
'companyid' => $useroutput['companyid'],
'userid' => $val,
'username' => $useroutput['username'][$key],
'password' => $useroutput['password'][$key],
];
}
