使用 MySQLi 时,是否必须执行一种while循环,将查询中的实际数据放入变量数组?
$conn = new mysqli($DBServer, $DBUser, $DBPass, $DBName);
// Check if able to connect to database
if ($conn->connect_error) {
trigger_error("Database connection failed: " . $conn->connect_error, E_USER_ERROR);
}
$sql = "SELECT name FROM users WHERE email = '$email'";
$rs = $conn->query($sql);
$numRows = $rs->num_rows();
我总是这样做:
$rs->data_seek(0);
while($row = $rs->fetch_assoc()) {
$name = $row['name'];
}
echo $name;
当只有一行时,是否有一种更方便的方法来回显查询数据?

如果只有一行,则不需要循环。只是做:
$row = $rs->fetch_assoc();
$name = $row['name'];
