Use PHP to download xls files (written by myself)_PHP tutorial
When I was looking at the ECSHOP source code yesterday, I came across something I had never learned before - how to use php to download xls files. Based on its source code, I implemented it and successfully achieved this effect.
Source code:
/*
*@Description: Download xls table
*
*
*/
function downloadXls($filename=''){
$filename = !empty($filename) ? $filename : die('nothing');
//The function of header is to create a new downloaded test.xls
header("Content-Type: application/vnd.ms-excel; charset=utf8" );
header("Content-Disposition: attachment; filename=$filename");
//The content that needs to be output here is directly output to the test.xls file
echo 'This is the test!';
exit;
}
$fileName = 'test.xls';
downloadXls($fileName);
?>
Effect:

Note: If the output is Chinese information, pay attention to the format conversion of character encoding!
But what if I want to download an xls file saved in the server?
After checking the php manual: I found that this function can be implemented very easily, using a readfile function. The code is as follows:
/*
*@Description :Download xls table
*
*
*/
function downloadXls($filename=''){
$filename = !empty($filename) ? $filename : die('nothing ');
//The function of header is to create a new downloaded test.xls
header("Content-Type: application/vnd.ms-excel; charset=utf8");
header("Content-Disposition: attachment; filename=$filename");
//Here is the file that needs to be output
readfile($filename);
}
$fileName = 'test.xls';
downloadXls($fileName);
?>
Effect:

Let’s expand a little further: What if I want to download a txt file, what about a pdf file?
The way to achieve this is to modify the content in Content-Type in the header output!
If there is anything missing, please point it out!

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,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
