Are there alternative or more efficient approaches to implementing gzip compression in PHP without directly modifying the source code?

When implementing gzip compression in PHP, one common approach is to modify the source code directly to add gzip headers and compress the output. However, an alternative and more efficient approach is to use server configurations like .htaccess or server-side settings to enable gzip compression without modifying the PHP source code.

// No PHP code snippet needed as the solution involves server configurations rather than PHP code modifications.
