## What it is
A curated collection of 149 PHP backend interview questions and answers, organized by topic (PHP 8, algorithms, networking, MySQL, Redis, architecture, security) with L1-L5 difficulty levels and frequency ratings. It is published as a static documentation site on GitHub Pages with runnable code examples.

## Use cases
- prepare for a PHP backend developer interview
- study PHP 8 interview questions and answers
- review MySQL and Redis concepts before an interview
- practice system design questions like short URL and flash sale systems
- learn data structures and algorithms for backend interviews
- brush up on web security topics like XSS and CSRF
- find a PHP developer roadmap for career growth

## When to choose
- you are a PHP developer preparing for technical interviews at any level from junior to architect
- you want structured, difficulty-graded Q&A with follow-up chains and code examples
- you need coverage of the full PHP backend stack including Laravel, Swoole, Nginx, and distributed systems

## When to avoid
- you need a runnable application, library, or tool rather than study material
- you are preparing for interviews in languages other than PHP
- you want interactive coding practice or automated assessment rather than reading material
