About the problem of generating text in php
Solution
Hello everyone, I have a problem
I have uploaded some data now, such as my personal information, etc. Then I want to add a "Download" button in the front desk. After clicking this button, the text I uploaded will be automatically generated from the server, and then downloaded and saved locally!
Does anyone know if there is any good way? It would be nice to give some tips, I have no clue now, I just learned programming not long ago!
Thank you!

.. What data did you upload? . bmp? php?
Reference answer
It's text! For example, a text like news, including title, date, content, etc. Is there any way?

The understanding ability is not very good. . I don’t understand what you are saying
Reference answer
This should be very simple, fopen---fwrite---fclose, you can refer to the text file writing code in the basic textbook.
Reference answer
I seem to know what you are going to do
//note: The directory where the file is located
$fileDir = './mydata';
//note: Check whether the directory is readable
if(!is_readable($fileDir)) {
die('Insufficient permissions');
}
//note: file initial array
$fileData = array();
//note:Read file
$handler = fopen($fileDir);
while(($filename = readdir($handler)) != FALSE){
if(!in_array($filename, array('.','..'), TRUE)) {
$fileData[]=file_get_contents($filename);
}
}
//note: For the operations you need, just use the $fileData array directly
Copy the code, I don’t know if it’s what you want
Reference answer
I haven't tried your code, but it doesn't look very good
Downloading a file does not require you to list the files in all directories and put them into an array
Owner, what do you need and how to download it?
How to display downloads in the frontend
If you want to directly display the path plus the file name, $filename = 'xiaoasp.txt'; //I'm testing here locally, you can use variables to get the file name using GET
Header("Content-type: application/force-download"); //Because txt files are parsed by the browser by default, they are forced to be downloaded
readfile($filename); //Then the output file
exit;
Copy code

Actually my idea is very simple, I just think:
On the background page, the news is uploaded to the server in the form of "title, date, author and content".
The fields on the server are id title date author content
In this way, I can watch my uploaded news in the front desk. This can be easily achieved using php.
But I suddenly thought about adding a "download" button in my background. The effect it wants to achieve is: after clicking, it will automatically upload all the news I uploaded to the server within a month (default) in the form of text or word Save it locally, so that I can read the news I uploaded before without going online in the future. Do you understand?
Of course, this is just an example, don't ask me why I don't save and then upload the news! Haha

Word format? It’s not that simple. Search the Internet for a PHP class that generates Word format files.

Text is fine, anything is fine, what I want is to be able to download it!

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
