6. Data is abstract/object relational mapping ORM
- ADOdb - database abstraction
- Doctrine - Object relational mapper (ORM), requires PHP 5.2.3+ version, a very powerful database abstraction layer (DBAL).
- Propel - Object-relational mapping framework - PHP5
- Outlet - is also a tool for object-relational mapping.
Note: Object Relational Mapping (ORM) is a technology designed to solve the mismatch between object-oriented and relational databases. Simply put, ORM automatically persists objects in a program into a relational database by using metadata that describes the mapping between objects and databases. Essentially, it converts data from one form to another. This also implies additional execution overhead; however, if the ORM is implemented as a middleware, there are many opportunities for optimizations that do not exist in a hand-written persistence layer. More importantly, the metadata used to control transformations needs to be provided and managed; but again, these costs are less than maintaining a handwritten solution; and even ODMG-compliant object databases still require class-level metadata.
7. PDF Generator
FPDF
This is a pure PHP library that allows you to generate PDF.
8. Excel related
- php-excel – This is a very simple Excel file generation class.
- PHP Excel Reader – can parse and read data in XLS files.

Give an example of storing an array in a PHP session.Apr 27, 2025 am 12:20 AMArrays 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.
How does garbage collection work for PHP sessions?Apr 27, 2025 am 12:19 AMPHP 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.
How can you trace session activity in PHP?Apr 27, 2025 am 12:10 AMTracking 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.

How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AMIn 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.
Explain how to use sessions for user authentication.Apr 26, 2025 am 12:04 AMThe 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.
