推荐答案

要得到期望的结果，最简单的方法是在我看来，这种方式：

The easiest way to get the result you expect is in my opinion this way:

$data = array(
    array(
        'domain' => 'messages',
        'key' => 'test.testik',
        'message' => array()
    ),
    array(
        'domain' => 'messages',
        'key' => 'test2313.tes31231tik',
        'message' => array()
    ),
    array(
        'domain' => 'validators',
        'key' => 'valid.validik',
        'message' => array()
    ),
    array(
        'domain' => 'validators',
        'key' => 'joga.jimbo',
        'message' => array()
    ),
    array(
        'domain' => 'validators',
        'key' => 'valid.validik',
        'message' => array()
    )
);
$newdata = array();

foreach ($data as $subdata) {
    $newdata[$subdata['key']] = $subdata;
}

$newdata = array_values($newdata); // reset array indizes 

print_r($newdata);
