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 Superglobals Get
🎯 한 줄 통찰 (One-line insight)
$_GET data can arrive via TWO independent paths that both end up in the same array — a manually-typed URL query string (?subject=PHP&web=...) and a form with method="GET" (which PHP automatically appends as a query string to the action URL) — meaning $_GET doesn't distinguish whether the data came from a link or a form submission. [S1]
🧠 핵심 개념 (Core concepts)
$_GET— array of variables from the HTTP GET method. [S1]- Two GET data sources — URL query strings (
?key=value&key2=value2) and HTML forms withmethod="get". [S1] - GET forms append to the URL — submitting a GET form results in
action_page.php?field1=value1&field2=value2visible in the address bar. [S1] - Security reminder — always sanitize with
htmlspecialchars(); proper validation belongs in the Form Validation chapter. [S1]
📖 세부 내용 (Details)
- Query string link:
<a href="demo_phpfile.php?subject=PHP&web=W3schools.com">Test $GET</a>→$subject = htmlspecialchars($_GET['subject']); $web = htmlspecialchars($_GET['web']);. [S1] - GET form:
<form action="welcome_get.php" method="GET"> Name: <input type="text" name="name"> E-mail: <input type="text" name="email"> <input type="submit"> </form>→ submitted URL becomeswelcome_get.php?name=John&email=john@example.com. [S1] - Retrieval:
Welcome <?php echo htmlspecialchars($_GET["name"]); ?><br> Your email address is: <?php echo htmlspecialchars($_GET["email"]); ?>. [S1]
⚖️ 모순 및 업데이트 (Contradictions & updates)
소스에서 모순되는 정보는 발견되지 않음.
🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 사용자 이름/이메일을 GET 폼으로 제출받아 인사말을 출력하는 것이 대표 실전 사례다. [S1]
💻 코드 패턴 (Code patterns)
Reading query string data via $_GET (PHP):
$subject = htmlspecialchars($_GET['subject']);
$web = htmlspecialchars($_GET['web']);
echo "Study $subject at $web.";
