When encountering encoding issues in PHP, functions like mb_convert_encoding and mb_detect_encoding can be used as potential solutions. mb_detect_encoding can help determine the current encoding of a string, while mb_convert_encoding can be used to convert a string from one encoding to another. By using these functions, you can ensure that your strings are correctly encoded and displayed.

// Example of using mb_detect_encoding and mb_convert_encoding to fix encoding issues
$string = "Sömè têxt wïth spécial chàràctèrs";

// Detect the current encoding of the string
$encoding = mb_detect_encoding($string);

// Convert the string to UTF-8 encoding
$utf8_string = mb_convert_encoding($string, 'UTF-8', $encoding);

echo $utf8_string;
