# [[PHP Looping Break]]

## 🎯 한 줄 통찰 (One-line insight)
`break` works identically across ALL four PHP loop types (for, while, do-while, foreach) — this chapter's entire purpose is to demonstrate that one keyword's behavior (immediately end the entire loop) generalizes uniformly regardless of which loop construct wraps it. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`break`** — immediately ends the entire loop's execution, regardless of loop type. [S1]
- **Applies uniformly to** — for, while, do...while, foreach. [S1]

## 📖 세부 내용 (Details)
- For: `for ($x = 0; $x < 10; $x++) { if ($x == 4) { break; } echo "The number is: $x <br>"; }`. [S1]
- While: `$x = 0; while($x < 10) { if ($x == 4) { break; } echo "The number is: $x <br>"; $x++; }`. [S1]
- Do-while: `$i = 1; do { if ($i == 3) break; echo $i; $i++; } while ($i < 6);`. [S1]
- Foreach: `foreach ($colors as $value) { if ($value == "blue") break; echo "$value<br>"; }`. [S1]

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

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 4가지 반복문 모두에서 동일하게 동작하는 break의 범용성이 핵심이다. [S1]

## 💻 코드 패턴 (Code patterns)
break behaves identically across loop types (PHP):
```php
for ($x = 0; $x < 10; $x++) {
    if ($x == 4) { break; }
    echo "The number is: $x <br>";
}
```
