在阵列中的位置

Question

我怎么能发现twoVal在第1位？

$arr = array('Cool Viski' => array('oneVal' => '169304',
                                   'twoVal' => '166678',
                                   'threeVal' => '45134'));

Answer 1

$position = array_search('twoVal', array_keys($arr['Cool Viski']));

Answer 2

尝试array_keys希望它能帮到你

$searchValue = "twoVal";
$keys = array_keys($array, $searchValue);
