# [[PHP OOP Destructor]]

## 🎯 한 줄 통찰 (One-line insight)
`__destruct()` runs automatically at the END of script execution (or when an object is explicitly destroyed) with NO explicit call needed — it's the structural mirror of `__construct()`, firing on the opposite lifecycle event (teardown vs. setup) rather than being invoked by user code. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`__destruct()`** — automatically called when an object is destroyed OR when the script finishes execution. [S1]
- **Opposite of `__construct()`** — fires at teardown instead of creation. [S1]
- **No arguments** — unlike the constructor, `__destruct()` takes no parameters. [S1]

## 📖 세부 내용 (Details)
- Constructor + destructor pair: `class Fruit { public $name; public $color; function __construct($name, $color) { $this->name = $name; $this->color = $color; } function __destruct() { echo "Name: " . $this->name . ". Color: " . $this->color .".<br>"; } } $apple = new Fruit('Apple', 'Red'); $banana = new Fruit('Banana', 'Yellow');` — the destructor for each object fires automatically at script end, printing both fruits' details even though `__destruct()` was never explicitly called. [S1]

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

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 생성자/소멸자 쌍이 코드 양을 줄이는 데 유용하다는 점이 팁으로 강조된다. [S1]

## 💻 코드 패턴 (Code patterns)
Destructor firing automatically at script end (PHP):
```php
class Fruit {
    public $name;
    public $color;
    function __construct($name, $color) {
        $this->name = $name;
        $this->color = $color;
    }
    function __destruct() {
        echo "Name: " . $this->name . ". Color: " . $this->color .".<br>";
    }
}
$apple = new Fruit('Apple', 'Red'); // __destruct() runs automatically at script end
```
