How can the encoding of PHP source code files affect the display of special characters in the output?

The encoding of PHP source code files can affect the display of special characters in the output if the encoding is not properly set. To ensure that special characters are displayed correctly, it is important to use a consistent encoding throughout the PHP files. One common encoding to use is UTF-8, which supports a wide range of special characters. 

// Set the encoding for PHP files to UTF-8
header('Content-Type: text/html; charset=utf-8');
ini_set('default_charset', 'utf-8');
