php - 我如何使用数组中的值？ (php)

Question

我想在数组的数组中使用值，例如:

$result  = $conn->query("SELECT performer,file_id,title,duration FROM 
    databasebot WHERE performer = '$message' or title = '$message'");

$poets = array(
    "keyboard" => array()
);


while ($row = mysqli_fetch_row($result)) {        
    $poets['keyboard'][] = array($row[2],$row[1]);         
}

我想回显$row[1] 的$poets 值。我该怎么做？

Answer 1

遍历 $poets['keyboard'] 中的数组。在每个元素中，$poets[1] 将位于 [1] 子元素中。

foreach ($poets['keyboard'] as $kb) {
    echo $kb[1];
}
