FAQ Section

Q: What's the difference between Thread Safe and Non-Thread Safe PHP?

A: Thread Safe (TS) versions are recommended for Windows when using Apache as a module. Non-Thread Safe (NTS) versions are typically used with FastCGI. For most Windows users, choose Thread Safe.

Q: Can I run multiple PHP versions simultaneously on Windows?

A: Yes, you can install multiple PHP versions in separate directories and switch between them by modifying your system PATH or using version management tools like phpenv for Windows.

Q: Why is my PHP installation showing errors about missing DLL files?

A: This usually indicates missing Visual C++ Redistributable packages. Download and install the appropriate Visual C++ Redistributable for your PHP version from Microsoft's website.

Q: How do I update PHP to a newer version on Windows?

A: For manual installations, download the new version, backup your current php.ini, extract the new version to your PHP directory, and restore your configuration. For XAMPP/WampServer, download the updated package.

Q: Is it safe to use PHP on Windows for production websites?

A: While PHP runs well on Windows, Linux is generally preferred for production environments due to better performance and security. Windows is excellent for development and testing purposes.

Q: How do I enable HTTPS/SSL for local PHP development on Windows?

A: You can enable SSL in XAMPP by starting Apache with SSL, or configure SSL certificates manually. Many developers use tools like mkcert to generate local SSL certificates for development.
