Combine multiple array with one array key - php

Question

I have a situation in PHP where I need to combine multiple array values and bind with the first array key, Let say I have following array,
[services] => Array
(
[0] => 1
[1] => 2
[2] => 1
)
[package_type] => Array
(
[0] => 1
[1] => 2
[2] => 1
)
[service_desc] => Array
(
[0] => Full HD
[1] => Full HD
[2] => Full HD
)
[service_price] => Array
(
[0] => 500
[1] => 600
[2] => 500
)
Now , I want to bind all array with service type keys like services[0] will have the value of package_type[0], service_desc[0] and service_price[0]. The purpose is that I can easily identify all service related values with its Id. Can anyone suggest ?

Answer 1

array_map is key here. Leave the first argument as null and it will group as you want:
<?php
$data =
[
'services' =>
[
'programming',
'debugging'
],
'description' =>
[
'the process of writing computer programs.',
'the process of identifying and removing errors from software/hardware'
]
];
$result = array_map(null, $data['services'], $data['description']);
var_export($result);
Output:
array (
0 =>
array (
0 => 'programming',
1 => 'the process of writing computer programs.',
),
1 =>
array (
0 => 'debugging',
1 => 'the process of identifying and removing errors from software/hardware',
),
)
Instead of writing out all your keys as arguments you could unpack like this:
array_map(null, ...array_values($data));
For something more elaborate, pass array_map a callable:
$keys = array_keys($data);
$result = array_map(function(...$args) use ($keys) {
return array_combine($keys, $args);
}, ...array_values($data));
var_export($result);
Output:
array (
0 =>
array (
'services' => 'programming',
'description' => 'the process of writing computer programs.',
),
1 =>
array (
'services' => 'debugging',
'description' => 'the process of identifying and removing errors from software/hardware',
),
)
