What are some common reasons for the error "Call to undefined function mb_detect_encoding()" in PHP?

The error "Call to undefined function mb_detect_encoding()" occurs when the Multibyte String extension (mbstring) is not enabled in PHP. To solve this issue, you need to enable the mbstring extension in your PHP configuration. 

<?php
// Check if the mbstring extension is enabled
if (!extension_loaded('mbstring')) {
    // Enable the mbstring extension
    if (function_exists('dl')) {
        dl('mbstring.so');
    } else {
        die('Please enable the mbstring extension in your php.ini file.');
    }
}

// Now you can use the mb_detect_encoding() function
?>
