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.
