Foreach循环输出字母而不是值

Question

我有下面的查询，我试图循环结果，但echo只返回数组的第二个字母而不是整个第二个数组。

$tsql = "SELECT UserId, Email FROM Membership";
$stmt = sqlsrv_query($conn, $tsql);
$row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_NUMERIC);
while ($row) {
    $body .= $row[0];
    foreach($row as $email)
    {
        echo $email[1]. "<BR>   ";
    }
}
;

Answer 1

你的代码有太多问题。你应该使用像

这样的东西

$tsql = "SELECT UserId, Email FROM Membership";

$stmt = sqlsrv_query($conn, $tsql);

while ($row = sqlsrv_fetch_assoc($stmt, SQLSRV_FETCH_ASSOC) ) {

        echo $row [UserId]. "<BR>   ";
        echo $row [Email ]. "<BR>   ";

};
