Retrieving Subdirectories from a Given Directory in PHP
Determining the subdirectories present within a specified directory often arises as a requirement in PHP programming. To effectively handle this task, you can leverage either the glob() function or a combination of glob() and array_filter().
Option 1: Utilizing glob() with GLOB_ONLYDIR
The glob() function, when used with the GLOB_ONLYDIR flag, offers a straightforward approach. This flag excludes files and the current (.), parent (..), and any directories beginning with a period (.), ensuring you solely obtain the subdirectories:
$subdirectories = glob('path/to/directory/*', GLOB_ONLYDIR);
Option 2: Leveraging array_filter() to Refine Results
Alternatively, you can combine glob() and array_filter() to filter out files and unwanted directories. However, this method may overlook directories that contain periods in their names, such as .config.
$directories = glob('path/to/directory/*'); $subdirectories = array_filter($directories, 'is_dir');
Applying the Function to Each Subdirectory
Once you have retrieved the subdirectories, you can apply a function to each of them using a loop:
foreach ($subdirectories as $subdirectory) { myFunction($subdirectory); }
By employing either of these options, you can efficiently gather the subdirectories within a specified directory and utilize them in your PHP code as needed.

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

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.

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),
