# [[PHP Install]]

## 🎯 한 줄 통찰 (One-line insight)
Most developers never need to "install" PHP at all — if a web host already supports it, dropping `.php` files into the web directory is sufficient, since the server parses them automatically; manual installation is only needed when running your own web server. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Two setup paths** — use a web host with existing PHP support (no setup needed), or install a web server + PHP + database (e.g. MySQL) yourself. [S1]
- **`phpversion()`** — function to check the installed PHP version. [S1]
- **Official resource** — php.net has installation instructions for self-hosted setups. [S1]

## 📖 세부 내용 (Details)
- Check version: `echo phpversion();`. [S1]

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

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — phpversion()으로 서버 환경의 PHP 버전을 확인하는 것이 실전에서 자주 쓰이는 진단 패턴이다. [S1]

## 💻 코드 패턴 (Code patterns)
Checking the installed PHP version (PHP):
```php
echo phpversion();
```
