Question

嗨我试图将PHP代码连接到mysql到会话用户，但我得到错误，我不知道是谁。我测试了这个没有运气

 SELECT * FROM .$_SESSION   ["username"]     WHERE Datouid......
 SELECT * FROM .$_SESSION   ["username"].    WHERE Datouid......
 SELECT * FROM  $_SESSION   ['username']     WHERE Datouid......
 SELECT * FROM .$_SESSION   ['username'].    WHERE Datouid......
 SELECT * FROM  $_SESSION   ['username'].    WHERE Datouid......
 SELECT * FROM  $_SESSION = ['username'].    WHERE Datouid......
 SELECT * FROM '$_SESSION = ['username']'    WHERE Datouid......
 SELECT * FROM '$_SESSION   ['username']'    WHERE Datouid......

我收到此错误：

注意：数组转换为字符串第43行/home/ar/public_html/TL/inc/incinput1.php 致命错误：未捕获mysqli_sql_exception：您的SQL中有错误句法;查看与您的MariaDB服务器版本对应的手册在＆＃39; [＆＃39;用户名＆＃39;]附近使用正确的语法。在哪里Datouid =＆＃39; 1＆＃39;＆＃39;在第1行

这是我需要提供错误的代码

$servername = "";

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

//connect to mysql database
try{
$conn =mysqli_connect($servername,$username,$password,$dbname);
}catch(MySQLi_Sql_Exception $ex){
echo("error in connecting");
}
//get data from the form
function getData()
