中奖信息
- 1
$sql = "select * from t_activity where MemberID='$memberID'";
$res = $db->GetData($sql);
while ($res)
{
}
$obj = mysqli_fetch_object($res);
?>
如上面,从数据库取出数据来后,怎么从数据库结果集中循环输出想要的数据在html的li里面?

大神就是大神!膜拜下!
还有个问题请教:
$sql = "select count(*) from t_activity where MemberID='$memberID'";
$res = $db->ExecSql($sql);
$num = mysqli_num_rows($res);
问下mysql,怎么统计查询count(*) 的行数,用上面的方法一直不成功!

打印出来1,但数据库有3条
打印出来1,但数据库有3条
把count(*)换成* 就可以了
或者这样也可以
$row = mysqli_fetch_row($res);$num = $row[0];

大神!
$num = mysqli_fetch_row($res);
echo $num[0];
或者
list($num) = mysqli_fetch_row($res);
或者
$num = crrrent(mysqli_fetch_row($res));

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
