Managing Gettext Translations on Shared Hosting
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.

Re-Introducing Symfony Console - CLI PHP for the Uninitiated!
Article Introduction：Core points
Symfony Console is a standalone package that provides a simple framework for creating command line tools, which is useful for repetitive tasks such as data migration, importing, or creating cron jobs.
To create a new command, you need to make the file executable. This can be done by creating a console file in the project root directory, ensuring the file is executable, and defining the console application.
You can use Symfony's CommandTester class to test commands, which provides special input and output classes to test commands without the command line.
Symfony Console is installed using Composer (the dependency management tool in PHP). It provides a simple

Using SPL Iterators, Part 1
Article Introduction：Core points
Iteration is a common process of traversing a list of values ??in programming. In PHP, an iterator is an object that traverses a list, such as an array, a directory list, or a database result set.
The standard PHP library (SPL) provides a large number of iterators that can make the code more efficient and readable. Using SPL iterators is especially advantageous when dealing with large amounts of data or complex structures beyond simple arrays.
ArrayIterator and RecursiveArrayIterator are two SPL iterators used to iterate over arrays. ArrayIterator is used for one-dimensional arrays, and RecursiveArrayIterator is used for multidimensional arrays.
