5. 断点续传原理是什么?怎么利用html5实现文件断点续传
简介:HTML5的FILE api,有一个slice方法,可以将BLOB对象进行分割。前端通过FileList对象获取到相应的文件,按照指定的分割方式将大文件分段,然后一段一段地传给后端,后端再按顺序一段段将文件进行拼接。

8. In-depth understanding of the special function __len__(self) in python
##Introduction: len If a class behaves like a list, to get the number of elements, you have to use the len() function. For the len() function to work properly, the class must provide a special method len(), which returns the number of elements. For example, we write a Students class and pass the name in:
9. Detailed explanation of Html5 datalist tag and dynamic matching with background data
Introduction: The new tag datalist in HTML5 enables automatic entry into the database fuzzy query when entering the first letter of Chinese/Pinyin, and returns the corresponding results. Generate a datalist, because when the input content in the input box changes, the datalist will automatically trigger the drop-down box. The solution is very good. I will share the example code with you through this article. Friends who need it can refer to it
10. Html5 new tag datalist implements detailed introduction of dynamic matching between input box and background database data
Introduction: The new tag datalist in HTML5 realizes that when the first letter of Chinese/Pinyin is entered, it automatically enters the database fuzzy query and returns the corresponding results to generate a datalist. When the input content in the input box changes , the datalist will automatically trigger the drop-down box. The solution is very good. I will share the example code with you through this article. Friends who need it can refer to it

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

Reasons 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.

Methods 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.

Multiple 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.

Configuring 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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
