What are common issues with character encoding in PHP websites?

Common issues with character encoding in PHP websites include displaying garbled text, incorrect character rendering, and data corruption. To solve this, it is important to ensure that the correct character encoding is specified in both the HTML meta tag and the PHP script.

// Set the character encoding in PHP
header('Content-Type: text/html; charset=utf-8');

// Set the character encoding in HTML
<meta charset="UTF-8">
