PHP

PHP is a server-side programming language often used to generate web pages and work with databases.

PHP runs on the server. It can generate HTML for a page or query a database to display dynamic content.

Changing PHP can affect server behavior such as login, saving, or payment, so it needs more care than plain HTML/CSS edits.

✅ Why it matters

• Widely used for dynamic pages and database-backed sites
• Easy to deploy on many hosting environments

⚠️ Limits and debates

• Server errors can break the whole page
• Weak security handling can be risky
