Convert an array with index and value into an array - php

Question

I have an array as key => value pair such as:
$array = [ 10 => 'Windows', 12 => 'Keyboard', 15 => 'Monitor' ];
What I would like to achieve without using any foreach or loops the following:
$converted = [
0 => [ 'id' => 10, 'name' => 'Windows'],
1 => [ 'id' => 12, 'name' => 'Keyboard'],
2 => [ 'id' => 15, 'name' => 'Monitor']
];
Here they indices in new array doesn't matter. Any tips??

Answer 1

No foreach and no loop, but now there is a closure:
$result = array_map(function ($id, $name) {
return [
'id' => $id,
'name' => $name
];
}, array_keys($array), array_values($array));
Even if there was a PHP function that did this exactly, it would be using a loop internally.
function do_what_ghazanfar_mir_wants(array $array) {
return array_map(function ($id, $name) {
return [
'id' => $id,
'name' => $name
];
}, array_keys($array), array_values($array));
}
And the single liner is:
$result = do_what_ghazanfar_mir_wants($array);
And the foreach approach for comparison:
$res = [];
foreach ($array as $id => $name) {
$res[] = [ 'id' => $id, 'name' => $name ];
}

If you want to keep it really short then array_walk will do it in one line:
array_walk($array, function(&$value, $key) { $value = ['id' => $key, 'name' => $value]; });
See https://3v4l.org/OEohi
But I think a foreach loop is probably going to be a lot more readable.

Do it with array_map(), Just pass the keys array_keys($array) and values $array as the parameter of your array_map()
<?php
$array = [ 10 => 'Windows', 12 => 'Keyboard', 15 => 'Monitor' ];
function map_by_key($m, $n)
{
return(array('id' => $m, 'name'=>$n));
}
$output = array_map("map_by_key", array_keys($array),$array);
print '<pre>';
print_r($output);
print '</pre>';
?>
