php - SQL查询只返回第一行

Question

我尝试显示选择查询的结果，但我只得到重复的第一行，而不是所有行。这是我的代码:

$query = "SELECT Email from client";
$result = $db->query($query)->fetch();
foreach($result as $email){
    echo $email["Email"]."\n";
}

与数据库的连接工作正常。

您只需要将fetchALL() 用作fetch() returns one row根据文档:

Fetches a row from a result set associated with a PDOStatement object.

$query = "SELECT Email from client";
$result = $db->query($query)->fetchALL();
foreach($result as $email){
    echo $email["Email"]."\n";
}
