PHP array value to key - php

Question

I have this array:
params {
[0] => {
name => "xxx"
value => "yyy"
}
[1] => {
name => "uuu"
value => "vvv"
}
}
and I want to achieve this:
params {
[0] => {
xxx => "yyy"
}
[1] => {
uuu => "vvv"
}
}
I can do it this way:
foreach ($params as &$param) {
$param[$param['name']] = $param['value'];
unset($param['name']);
unset($param['value']);
unset($param);
}
But I am wondering if this could be done on more elegant way?

Answer 1

This calls for an array mapping of values:
$params = array_map(function ($i) { return [$i['name'] => $i['value']]; }, $params);

Answer 2

You can use array_map to reiterate the array.
$params = [
[
'name' => "xxx",
'value' => "yyy"
],
[
'name' => "uuu",
'value' => "vvv"
]
];
$params = array_map(function($o){
return [ $o['name'] => $o['value'] ];
}, $params);
echo "<pre>";
print_r( $params );
echo "</pre>";
This will result to:
Array
(
[0] => Array
(
[xxx] => yyy
)
[1] => Array
(
[uuu] => vvv
)
)

Answer 3

This is a bit shorter. By not using foreach you can directly replace the elements.
for ($i = 0; $i < count ($params); $i++)
$params[$i] = array ($params[$i]['name'] => $params[$i]['value']);

Answer 4

To make your current code a little bit more elegant, you could pass multiple arguments to unset
foreach ($params as &$param) {
$param[$param['name']] = $param['value'];
unset($param['name'], $param['value'], $param);
}

Answer 5

Try this :
foreach ($params as $key => $sub_array) {
// unset original array data
unset($params[$key]);
// construct the new values
$params[$key][$sub_array['name']] = $sub_array['value'];
}
EDIT:
Another approach more elegant is the following :
foreach($params as $k=>$s){
$params[$k]=array($s['name']=>$s['value']);
}

Answer 6

Please try this:
foreach ($params as $k => $v)
{
$nary[$v[name]] = $v[value];
}
$params = $nary;
