How can PHP handle encoding issues when using string comparison functions like strpos() or strstr() on UTF-8 text?

When using string comparison functions like strpos() or strstr() on UTF-8 text, PHP may encounter encoding issues due to the multi-byte nature of UTF-8 characters. To handle this, you can use the mb_strpos() and mb_strstr() functions from the Multibyte String extension in PHP. These functions are specifically designed to work with multi-byte character encodings like UTF-8. 

// Example code snippet using mb_strpos() to handle encoding issues with UTF-8 text
$text = "Hello, 世界";
$needle = "世界";

if(mb_strpos($text, $needle) !== false) {
    echo "Needle found in haystack!";
} else {
    echo "Needle not found in haystack.";
}
