How can UTF-8 encoding be implemented in PHP to prevent issues with special characters?

Special characters can cause encoding issues in PHP, especially when using UTF-8 encoding. To prevent these issues, it's important to ensure that your PHP files are saved with UTF-8 encoding and that your server is configured to handle UTF-8 characters properly. Additionally, you can use the mb_internal_encoding() function in PHP to set the internal encoding to UTF-8, ensuring that all string functions operate in the correct encoding. 

// Set internal encoding to UTF-8
mb_internal_encoding("UTF-8");

// Sample code to handle special characters
$text = "Café";
echo $text;
