What are the advantages and disadvantages of using include statements for language-specific content in PHP websites?

When working on PHP websites, including language-specific content using include statements can help keep code organized and make it easier to manage translations. However, using include statements for language-specific content can also lead to code duplication and maintenance issues if not implemented carefully.

// Example of including language-specific content using include statements

// English content
include 'lang/en.php';

// French content
include 'lang/fr.php';
