# [[PHP Tutorial]]

## 🎯 한 줄 통찰 (One-line insight)
Map of Content (MOC) for the W3Schools PHP Tutorial — the root that links every core-PHP-language knowledge page in this topic folder. [S1]

## 🧠 핵심 개념 (Core concepts)
- This folder (`Topic_PHP`) wikifies the core PHP language tutorial, one knowledge page per document, in P-Reinforce v3.1 format — same convention as `Topic_SQL` / `Topic_Python` / `Topic_Java` / `Topic_HTML` / `Topic_CSS` / `Topic_JavaScript`. [S1]
- Scope: **tutorial pages only**. Explicitly **excluded**: reference dumps (`php_ref_*` index pages and all `func_*`/`keyword_*`/`ref_exception_*` detail pages), meta pages (Exam/Examples/Compiler/Quiz/Exercises/Server/Syllabus/Study Plan). [S1]
- **Included despite overlapping category names**: `php_mysql_*` (PHP-specific mysqli usage, distinct from a general MYSQL category) and `php_xml_*` (PHP-specific XML parsing via SimpleXML/DOM/Expat, distinct from a general XML syntax category) and `php_json.asp` (PHP's json_encode/decode usage, distinct from a general JSON category) — same precedent as Python_MySQL/Python_MongoDB staying in Topic_Python. [S1]
- **Progress:** **114 of 114 planned docs complete — PHP category done.**
- Every page roots its Knowledge Graph back to this `[[PHP Tutorial]]` node.
