PHP - 将数组值存储在变量中

Question

如何从查询数组结果集中获取值并将其故事记录在另一个变量中，这是我的尝试：

$countEps = Singlequery('SELECT COUNT(1) AS num_eps FROM items WHERE name = :name',
                            array('name' => $_GET['name'], ), $conn);


// Store the number of episodes
$ep = $num_eps;

这是查询返回的内容：

Array ( [0] => Array ( [num_eps] => 15 ) )

Answer 1

你应该这样做

print_r($countEps);
$ep = array();
foreach($countEps as $value){
$ep = array('num_eps' => $value['num_eps'])}
print_r($ep);
