# [[PHP If Shorthand]]

## 🎯 한 줄 통찰 (One-line insight)
The one-line `if` (without braces or else) and the ternary `if...else` shorthand are TWO DIFFERENT techniques with different syntax — the former just omits braces for a single statement (`if ($a < 10) $b = "Hello";`), while the latter is the `?:` ternary/conditional-expression form (`$b = $a < 10 ? "Hello" : "Good Bye";`), and they aren't interchangeable. [S1]

## 🧠 핵심 개념 (Core concepts)
- **One-line if** — braces can be omitted for a single statement: `if (condition) statement;`. [S1]
- **Ternary operator (`?:`)** — the shorthand for if...else: `$result = condition ? valueIfTrue : valueIfFalse;`. [S1]
- **Also called** — "Ternary Operators" or "Conditional Expressions." [S1]

## 📖 세부 내용 (Details)
- One-line if: `$a = 5; if ($a < 10) $b = "Hello"; echo $b;`. [S1]
- Ternary if...else: `$a = 13; $b = $a < 10 ? "Hello" : "Good Bye"; echo $b;`. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
소스에서 모순되는 정보는 발견되지 않음.

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 짧은 이진 분기를 한 줄로 표현하는 삼항 연산자가 실전 코드에서 자주 쓰인다. [S1]

## 💻 코드 패턴 (Code patterns)
Ternary operator as if...else shorthand (PHP):
```php
$a = 13;
$b = $a < 10 ? "Hello" : "Good Bye";
echo $b;
```
