我在 SQL 部分使用了 mysqli。如果您想知道 SQL 查询，那就是选择最新记录。 任何人都可以就此提出建议吗？如果有请分享。提前谢谢。
P.S：也出现这个错误：
Fatal error: Uncaught Error: Call to undefined function mysql_query() in C:\xampp\htdocs\smartParking\slotstatus.php:192 Stack trace: #0 main thrown in C:\xampp\htdocs\smartParking\slotstatus.php on line 192
【问题讨论】：
mysql_query 在 PHP 5 中已弃用，在 PHP 7 中已完全删除。请改用 PDO 或 mysqli。
【参考方案1】：
您正在运行哪个版本的 PHP ？ mysql已经贬值了。
在您的代码中从 mysql 更改为 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))
【讨论】：
我使用的是 PHP 7.2.6。所以我想我必须听从你的建议。谢谢。【参考方案2】：使用 mysqli_query() 和 mysqli_fetch_array()，新版本的 PHP 不支持 'mysql' 函数。
【讨论】：
【参考方案3】：错误消息表明您正在使用mysql_query 进行调用 mysql_query 自 PHP 5.5 起已被弃用。而是尝试；
$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']);
【讨论】：
我尝试了解决方案。然后出现错误：Fatal error: Uncaught Error: Call to a member function fetch_assoc() on boolean in C:\xampp\htdocs\smartParking\slotstatus.php:208 Stack trace: #0 main thrown in C:\xampp\htdocs\smartParking\slotstatus.php on line 208以上是关于PHP脚本未加载托管在xampp中的[重复]的主要内容，如果未能解决你的问题，请参考以下文章
