This article mainly introduces the function of batch uploading table data in Thinkphp5 PHPExcel. Friends who need it can refer to it
1. First, download PHPExcel and put it in the vendor folder. My path is: project/ vendor/PHPExcel/, put the downloaded PHPExcel file here
2. Front-end code
<!DOCTYPE html>
<html>
<head>
<title>批量导入数据</title>
</head>
<body>
<form action="{:url('/index/index/importExcel')}" method="post" enctype="multipart/form-data">
<input type="file" name="myfile"><br/>
<input type="submit" value="批量的导入">
</form>
</body>
</html>
3.Backend code
/**
* 导入表格数据
* 先把文件上传到服务器，然后再读取数据存到数据库
*/
public function importExcel(){
header("content-type:text/html;charset=utf-8");
//上传excel文件
$file = request()->file('myfile');
//移到/public/uploads/excel/下
$info = $file->move(ROOT_PATH.'public'.DS.'uploads'.DS.'excel');
//上传文件成功
if ($info) {
//引入PHPExcel类
vendor('PHPExcel.PHPExcel.Reader.Excel5');
//获取上传后的文件名
$fileName = $info->getSaveName();
//文件路径
$filePath = 'public/uploads/excel/'.$fileName;
//实例化PHPExcel类
$PHPReader = new \PHPExcel_Reader_Excel5();
//读取excel文件
$objPHPExcel = $PHPReader->load($filePath);
//读取excel文件中的第一个工作表
$sheet = $objPHPExcel->getSheet(0);
$allRow = $sheet->getHighestRow(); //取得总行数
//$allColumn = $sheet->getHighestColumn(); //取得总列数
//从第二行开始插入，第一行是列名
for ($j=2; $j <= $allRow; $j++) {
$data['name'] = $objPHPExcel->getActiveSheet()->getCell("A".$j)->getValue();
$data['tel'] = $objPHPExcel->getActiveSheet()->getCell("B".$j)->getValue();
$data['addr'] = $objPHPExcel->getActiveSheet()->getCell("C".$j)->getValue();
$last_id = Db::table('users')->insertGetId($data);//保存数据，并返回主键id
if ($last_id) {
echo "第".$j."行导入成功，users表第:".$last_id."条！<br/>";
}else{
echo "第".$j."行导入失败！<br/>";
}
}
}else{
echo "上传文件失败！";
}
}
Output result:
Note:
Introducing a third-party class library using vendor(); is in the form of a namespace. The underlying code will automatically replace "." with "/", so when using "/", use "." instead;
The above code can be copied and used directly, but the database related information must be changed to your own !

What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AMReasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.
How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AMMethods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.
What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AMMultiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.
How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AMConfiguring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.
What are the advantages of using a database to store sessions?Apr 24, 2025 am 12:16 AMThe main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.
How do you implement custom session handling in PHP?Apr 24, 2025 am 12:16 AMImplementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.
What is a session ID?Apr 24, 2025 am 12:13 AMSessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.
How do you handle sessions in a stateless environment (e.g., API)?Apr 24, 2025 am 12:12 AMManaging sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.
