Replace array by specific element value - php

Question

I need to replace my main array elements by 'employee_id'.
I already tried array_replace_recursive() function But It replaces arrays by the default index value.
$merged = array_replace_recursive($empList, $getworkedHrs,
$getErrAttnds);
The arrays look like this:
$empList
array (
0 =>
array (
'employee_id' => '254',
'emp_name' => 'Mary McDonald',
'worked_days' => 0,
'worked_hours' => 0,
'error_attendance' => 0,
),
1 =>
array (
'employee_id' => '255',
'emp_name' => 'Anthony Coffman',
'worked_days' => 0,
'worked_hours' => 0,
'error_attendance' => 0,
),
2 =>
array (
'employee_id' => '316',
'emp_name' => 'cheth aruno',
'worked_days' => 0,
'worked_hours' => 0,
'error_attendance' => 0,
),
)
2nd Array: $getworkedHrs
array (
0 =>
array (
'employee_id' => '254',
'worked_days' => '22',
'worked_hours' => '7.0',
),
1 =>
array (
'employee_id' => '255',
'worked_days' => '8',
'worked_hours' => '7.0',
),
)
3rd array : $getErrAttnds
array (
0 =>
array (
'employee_id' => '316',
'error_attendance' => '1',
),
)
Expected Result Array:
array (
0 =>
array (
'employee_id' => '254',
'emp_name' => 'Mary McDonald',
'worked_days' => 22,
'worked_hours' => 7.0,
'error_attendance' => 0,
),
1 =>
array (
'employee_id' => '255',
'emp_name' => 'Anthony Coffman',
'worked_days' => 8,
'worked_hours' => 7.0,
'error_attendance' => 0,
),
2 =>
array (
'employee_id' => '316',
'emp_name' => 'cheth aruno',
'worked_days' => 0,
'worked_hours' => 0,
'error_attendance' => 1,
),
)

Answer 1

I believe the simplest solution is to merge them in two foreach.
First make the main array associative so that it's easier to get the correct employee.
Then loop the arrays and copy the values.
$empList = array_column($empList, null, 'employee_id');
foreach($getworkedHrs as $entry){
$empList[$entry['employee_id']]['worked_days'] = $entry['worked_days'];
$empList[$entry['employee_id']]['worked_hours'] = $entry['worked_hours'];
}
foreach($getErrAttnds as $entry){
$empList[$entry['employee_id']]['error_attendance'] = $entry['error_attendance'];
}
var_export($empList);
