获取数组元素

Question

This problem is old and basic but I can't figure out a better way to get it right without looping through the whole array

$a=array(
'a'=>array
    (
      'x'=>'something',
      'y'=>'somethingelse',
      'z'=>'another thing'
    );
);

I would like to get the value of 'y' key.

I try this

foreach($a as $k=>$v)
{
  foreach($v as $vv)
  {
    return $v['y']
  }
}

UPDATE
Thanks for your posts. How stupid I am :shy:

Answer 1

echo $a['a']['y'];

This is me adding characters to reach the 30 char minimum.
