为什么我不应该在php中使用mysql函数(12个答案）
两年前关门了。
我在xampp中有一个小型网站主机。我使用的是最新版本的xampp。但是当我在web浏览器上输入url时，该php页面根本没有加载。其他页面加载时没有任何问题。以下是完整代码：

我将mysqli用于sql部分。如果您想知道sql查询，那就是选择最新的记录。有谁能给我一些建议吗？如果有，请分享。谢谢。
p、 s:这个错误也发生在：

错误消息表明您正在使用 mysql_query mysql\u query在php5.5中已经被弃用。相反，尝试；

$mysqli = new mysqli("example.com", "user", "password", "database");
$result = $mysqli->query("SELECT 'Hello, dear MySQL user!' AS _message FROM DUAL");
$row = $result->fetch_assoc();
echo htmlentities($row['_message']);

您正在运行哪个版本的php？mysql已经贬值了。
在代码中从mysql改为mysqli
你的代码似乎还有mysql，检查！

$result = mysql_query($success,"SELECT sensorId,slotStatus,time FROM arduino_ultrasonic au1 WHERE timestamp = (SELECT MAX(timestamp) FROM arduino_ultrasonic au2 WHERE au1.sensorId = au2.sensorId)");
while($row = mysql_fetch_array($result))

使用mysqli_query（）和mysqli_fetch_array（），新版本的php不支持“mysql”函数。
