PHP Sessions
🎯 한 줄 통찰 (One-line insight)
A session's ONLY client-side footprint is a small random ID stored in a PHPSESSID cookie — the actual session DATA lives entirely on the server (typically in a temp file), meaning sessions are fundamentally more secure than cookies for sensitive data, since the browser never holds the real information, just a lookup key. [S1]
🧠 핵심 개념 (Core concepts)
- Session — solves HTTP's statelessness by storing per-user data server-side, linked via a client-side ID cookie. [S1]
session_start()— must be called at the very beginning of every script using sessions, before ANY HTML output or whitespace. [S1]$_SESSION— superglobal for storing/accessing session variables. [S1]unset($_SESSION["key"])— removes one session variable. [S1]session_unset()— clears ALL session variables. [S1]session_destroy()— destroys all data tied to the current session entirely. [S1]- Default lifetime — session data persists until the browser closes (unlike cookies, which can have a long fixed expiration). [S1]
- Sessions vs. cookies — sessions: server-stored, more secure, closes-on-browser-close, more efficient (no repeated data transfer); cookies: browser-stored, less secure, long expiration possible, less efficient (sent with every request). [S1]
📖 세부 내용 (Details)
- Start + set variables:
session_start(); $_SESSION["favcolor"] = "green"; $_SESSION["favanimal"] = "cat";. [S1] - Retrieve on another page:
session_start(); if(isset($_SESSION["favcolor"])) { echo $_SESSION["favcolor"]; }. [S1] - Modify: overwrite directly —
$_SESSION["favcolor"] = "yellow";. [S1] - Destroy (logout):
session_start(); session_unset(); session_destroy(); echo "You have been logged out.";. [S1] - Debug all values:
print_r($_SESSION);. [S1]
⚖️ 모순 및 업데이트 (Contradictions & updates)
소스에서 모순되는 정보는 발견되지 않음.
🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — session_unset()+session_destroy() 조합으로 로그아웃을 구현하는 것이 실전 인증 시스템의 표준 패턴이다. [S1]
💻 코드 패턴 (Code patterns)
Logging out by clearing all session data (PHP):
session_start();
session_unset();
session_destroy();
echo "You have been logged out.";
