PHP is old. Many use it for web apps. The problem is not the language. Bad structure and poor security are the real issues.

Modern PHP works for business websites and APIs.

Stop writing everything from scratch. Use a framework. Frameworks handle routing and authentication.

• Laravel for APIs.
• Symfony for enterprise apps.
• CodeIgniter for simple projects.

Frameworks stop repetitive work.

Stop putting everything in one file. Separate your code.

• Routes
• Controllers
• Models
• Views

This makes debugging easy.

Stop SQL injection. Use prepared statements. Separate SQL logic from user input.

Protect passwords. Use password_hash and password_verify. Avoid MD5 or SHA1.

Treat all input as unsafe. Validate every form.

Stop XSS. Escape output using htmlspecialchars.

Secure your sessions. Use secure cookie settings. Regenerate IDs after login.

Add CSRF tokens to forms.
