How can the output encoding be changed in PHP to resolve character encoding issues when displaying text?

When displaying text in PHP, character encoding issues can arise if the output encoding is not set correctly. To resolve this, you can change the output encoding using the header() function in PHP. By setting the correct encoding, you can ensure that the text is displayed properly without any character encoding problems.

// Set the output encoding to UTF-8
header('Content-Type: text/html; charset=utf-8');
