Article Introduction：Core points Gettext is a popular method for translation management of PHP websites, but it has a significant drawback: Apache caches translations, which means that unless the engine is restarted, updates to translated files will not be visible. This is especially problematic on shared hosting, as administrator privileges are often not available. Audero Shared Gettext is a PHP library that allows developers to bypass Apache's cache of translations loaded through the gettext() function. The library uses a simple trick to create a mirrored copy of the translation file, tricking Apache into thinking it as a new, irrelevant translation, thus avoiding caching issues. Audero Shared Gettext available

Article Introduction：This article discusses in-depth the issue that the client browser may not be able to obtain the latest data in a timely manner due to the caching mechanism after JSON file updates in PHP applications. The article will explain in detail how browser caching works, clarify the difference between PHP server-side file reading and client resource request, and provide an effective solution - cache Busting strategy, which forces the browser to reload the updated JSON file by attaching a dynamic version number to the resource URL, thereby optimizing the user experience and ensuring data synchronization.

Article Introduction：While PHP is known for building web pages and applications, it has much more than that. I recently needed to dynamically extract an audio from a WAV file and allow the user to download it through the browser. I tried to find a library that suited my needs, but I didn't succeed and had to write my own code. This is a great opportunity to dig into WAV file structure. In this post, I will briefly outline the WAV file format and explain the library I developed: Audero Wav Extractor. Key Points Waveform Audio File Format (WAV) is a standard used by Microsoft to store digital audio data, consisting of blocks representing different parts of an audio file. "RIFF", "Fmt" and "Data" are the heaviest

Article Introduction：The core method of reading CSV files in Go language is to use the standard library encoding/csv. The specific steps are as follows: 1. Open the file and create a CSVreader with os.Open; 2. Read the data using reader.ReadAll() or line-by-line Read() method; 3. Handle possible format problems, such as quotes, comma nesting, blank lines, etc.; 4. CSV data can be mapped to the structure through a third-party library (such as gocsv) to improve operability. The whole process is simple and direct, but attention should be paid to details such as field order, format consistency and error handling.

Article Introduction：Reading CSV files can be implemented in Python through the csv module and pandas library. Use the csv module without dependencies, and is suitable for simple scenarios. The example code is: importcsvwithopen('data.csv',mode='r',encoding='utf-8')asfile:reader=csv.DictReader(file)forrowinreader:print(row), which can read data and output it in dictionary; if you need a list form, csv.reader() can be used. Pandas is more efficient and is especially suitable for data analysis. The sample code is: importpan

Article Introduction：Boost.Asio is a powerful library for C network programming, supports TCP, UDP and serial communications, and provides cross-platform asynchronous I/O models. 1. First install Boost and link the boost_system library or use header file mode to include. 2. To write a simple TCP server, you need to create io_context, tcp::acceptor and accept connections and echo data synchronously in the loop. 3. The asynchronous server uses async_accept, async_read_some and async_write in conjunction with lambda callbacks, and starts event loops through io.run() to achieve high concurrency. 4. TCP client passes tcp::res
