阵列中的位置

Question

我怎么能发现twoVal在位置1？

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

Answer 1

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

尝试array_keys希望它会帮助你

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