Take a chestnut :

// Suppose there is an array as follows 
$arr = [
    [
        'id' => '100',
        'name' => 'boy',
        'val' => 'handsome',
    ],
    [
        'id' => '200',
        'name' => 'girl',
        'val' => 'beautiful',
    ],
];
// Expect to name Raise as key value ,  The operation is as follows 
$re = array_column($arr, null, 'name');
print_r($re); // give the result as follows 

[
    'boy' => [
        'id' => '100',
        'name' => 'boy',
        'val' => 'handsome',
    ],
    'girl' => [
        'id' => '200',
        'name' => 'girl',
        'val' => 'beautiful',
    ],
];
