PHP Comments Multiline

🎯 한 줄 통찰 (One-line insight)

Multi-line comment syntax (/* ... */) can be embedded MID-STATEMENT, not just around whole lines — $x = 5 /* + 15 */ + 5; shows the comment silently removing a piece of an expression, letting you selectively "comment out" a sub-part of a calculation without touching the rest of the line. [S1]

🧠 핵심 개념 (Core concepts)

• /* ... */ — multi-line comment; all text between the delimiters is ignored. [S1]
• Block-disabling — wrapping multiple lines of code in /* */ disables the entire block at once. [S1]
• Mid-expression use — the same syntax can remove just a fragment of a single line/expression. [S1]

📖 세부 내용 (Details)

• Explanatory comment: /* The next statement will print a welcome message */ echo 'Welcome Home!';. [S1]
• Disabling a code block: /* echo 'Welcome to my home!'; echo 'Mi casa su casa!'; */ echo 'Hello!'; — only "Hello!" prints. [S1]
• Mid-line fragment removal: $x = 5 /* + 15 */ + 5; echo $x; // 10, not 25. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 계산식 일부를 임시로 제외하고 테스트하는 것이 실전에서 자주 쓰이는 디버깅 기법이다. [S1]

💻 코드 패턴 (Code patterns)

Mid-expression comment removing part of a calculation (PHP):

$x = 5 /* + 15 */ + 5;
echo $x; // 10
