PHP - 将多维数组转换为2D数组

Question

我有一个像这样多维的数组

array(
    0 => array(
        'User' => array(
                 'email' => 'test@yahoo.com ,testuser@yahoo.com',
                 'username' => 'test,testuser',
                 'description' => 'description1,description2'   
                  )   
         )
);

我想将此数组转换为此表单

$User = array(
    'email' => array(
        'test@yahoo.com',
        'testuser@yahoo.com'
    ),
    'username' => array(
        'test',
        'testuser'
    ),
    'description' => array(
        'description1',
        'description2'
    )
);

请帮忙!!!

仅适用于一个指数:

$arrayTwoD = array();
foreach ($valueMult[0]['User'] as $key => $value) { 
    $arrayTwoD[$key] = array_push(explode(',', $value));
}

如果您有多个索引$multArray:

$arrayTwoD = array();
foreach ($multArray as $keyMult => $valueMult) { 
    foreach ($valueMult['User'] as $key => $value) { 
        $arrayTwoD[$keyMult][$key] = array_push(explode(',', $value));
    }
}

要么

$arrayTwoD = array();
foreach ($multArray as $array) { 
    foreach ($array['User'] as $key => $value) { 
        $arrayTwoD[$key] = array_push(explode(',', $value));
    }
}
