这是来自 php pdo 查询的结果数组。
我怎样才能得到例如只有sitetitle
“ langCode
en”的?
Array
( [0] => Array ( [id] => 3 [alias] => home [sitetitle] => LALALA [langCode] => de [langName] => Deutsch ) [1] => Array ( [id] => 3 [alias] => home [sitetitle] => LOLOLO [langCode] => en [langName] => English ) [2] => Array ( [id] => 3 [alias] => home [sitetitle] => LELELE [langCode] => es [langName] => Español )
)
