Antigravity Agent e9cbf23ab5 docs(10_Wiki): Dev 폴더 누락분 반영 — Topic_Programming으로 통합
이전 재구성 작업에서 Dev/ 폴더가 누락되었던 것을 반영.

- Dev/Topic_Programming(중첩 폴더, 78개)은 Dev 자체 최상위 폴더들
  (Architecture/Conventions/Engineering_Intelligence 등)과 완전 중복이라 제거.
- Dev 최상위 엔지니어링 지식 폴더(Architecture/Conventions/Engineering_Intelligence/
  Failure_Library/Generalized_Principles/Language/Pattern_Catalog/Platform_Guides/
  Subsystems, 77개)는 이미 Topic_Programming/Topic_Programming에 더 최신 버전이
  존재해 중복 제거(고유 콘텐츠 1개는 예외 처리하여 이동 보존).
- Dev의 W3Schools 언어 튜토리얼 폴더(Topic_C/CPP/CSS/CSharp/HOWTO/HTML/Java/
  JavaScript/PHP/Python/SQL/W3CSS, 1201개)는 전부 Topic_Programming 하위로 이동.
- 에이전트 운영 상태(.astra/docs)는 그대로 유지, 콘텐츠 폴더만 정리.
- Topic_Programming 최종 문서 수: 2784 → 3985.

PHP Forms

🎯 한 줄 통찰 (One-line insight)

GET data is visible in the URL and bookmarkable, but capped at ~2000 characters and NEVER safe for passwords — while POST data is invisible in the URL (no bookmarking) but has no size limit and supports file uploads — meaning the "developer preference for POST" isn't arbitrary, it directly follows from these visibility/size/capability trade-offs. [S1]

🧠 핵심 개념 (Core concepts)

  • $_GET / $_POST — superglobal arrays collecting form data by the name attribute as key. [S1]
  • GET — data visible in URL; ~2000 character limit; bookmarkable; NEVER use for passwords/sensitive data. [S1]
  • POST — data invisible (embedded in request body); no size limit; supports file uploads (multi-part binary). [S1]
  • No validation shown yet — this chapter demonstrates the mechanics only; security/validation comes in later chapters. [S1]

📖 세부 내용 (Details)

  • POST form: <form action="welcome.php" method="post"> Name: <input type="text" name="name"><br> .... [S1]
  • Retrieval: echo $_POST["name"]; echo $_POST["email"];. [S1]
  • GET form equivalent: <form action="welcome_get.php" method="get"> ... retrieved via $_GET["name"]. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

  • GET의 보안 경고: 비밀번호 등 민감한 정보는 절대 GET으로 전송해서는 안 된다는 점이 강하게 경고됨. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 이 챕터의 예제는 검증 없는 기초 폼 처리이며, 다음 챕터부터 보안을 고려한 검증이 다뤄진다. [S1]

💻 코드 패턴 (Code patterns)

Basic POST form and retrieval (PHP/HTML):

<form action="welcome.php" method="post">
    Name: <input type="text" name="name"><br>
    <input type="submit">
</form>
echo $_POST["name"];
