How to import Excel into the database and export database data to Excel with PHP, and export excel data
This article describes the method of importing Excel into the database and exporting database data to Excel with PHP. Share it with everyone for your reference. The specific implementation method is as follows:
1. Import
Importing requires the use of components that can read Excel. There are also better components on the Internet. Here I share the ones I use: Download Extraction code: vxyn. (Note that the two files are referenced)
<?php //传入要导入的Excel的文件名 function import_to_DB($filename) { require_once'reader.php'; $data = new Spreadsheet_Excel_Reader(); //创建读取Excel的对象 $data->setOutputEncoding('utf-8'); //设置读取Excel内容后输出的字符编码 $data->read("data/Excel/{$filename}.xls"); $db = mysql_connect('localhost', '用户名', '密码') or die("Could not connect to database."); //连接数据库 mysql_query("set names 'uft8'"); //输出中文 mysql_select_db('数据库名'); //选择数据库 error_reporting(E_ALL ^ E_NOTICE); for ($i = 1; $i <= $data->sheets[0]['numRows']; $i++) { echo $data->sheets[0]['cells'][$i][列数]; //这里可以把每一行相应列的值插到数据库中,如: /* $sql="insert "表名" values(对应项...)"; mysql_query($sql); 可加上错误判断 */ } ?>
In short, if you can read the value of the corresponding column $data->sheets[0][row][column] in each row of the table, the insertion operation will be easy.
2. Export
Export can easily export table files using the MIME protocol without relying on any components. Set the header in the following format to export to Excel, and the browser will download it at the same time
header('Content-type: text/html; charset=utf-8'); header("Content-type:application/vnd.ms-excel;charset=UTF-8"); //application/vnd.ms-excel指定输出Excel格式 header("Content-Disposition:filename=表格文件名.xls"); //输出的表格名称
The complete code is as follows:
<?php header('Content-type: text/html; charset=utf-8'); header("Content-type:application/vnd.ms-excel;charset=UTF-8"); header("Content-Disposition:filename=表格文件名.xls"); $conn = mysql_connect("localhost","root","数据库密码") or die("不能连接数据库"); mysql_select_db("数据库名", $conn); mysql_query("set names 'UTF-8'"); $sql="select * from 表名 where 条件"; $result=mysql_query($sql); echo "表头1\t表头2\t表头3\n"; while($row=mysql_fetch_array($result)){ echo $row[0]."\t".$row[1]."\t".$row[2]."\n"; } ?>
Here, t is actually a format change, and n is a line break. Set the link to this php file in a web page, and when clicked, the browser will automatically save the passed stream as an Excel file.
I hope this article will be helpful to everyone’s PHP programming design.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.

In PHP, you can effectively prevent CSRF attacks by using unpredictable tokens. Specific methods include: 1. Generate and embed CSRF tokens in the form; 2. Verify the validity of the token when processing the request.
