What is the difference between urlencoding and utf-8 encoding in PHP?

URL encoding is used to encode special characters in a URL to ensure they are properly interpreted by web browsers. UTF-8 encoding, on the other hand, is a character encoding standard that allows for the representation of a wide range of characters from various languages. In PHP, you can use the urlencode() function to URL encode a string and the utf8_encode() function to UTF-8 encode a string.

// URL encode a string
$urlEncodedString = urlencode($string);

// UTF-8 encode a string
$utf8EncodedString = utf8_encode($string);
