Answer / Sarfaraj Khan
urlencode() is a PHP function that encodes a string into a format suitable for use in a URL. It replaces characters such as spaces, certain punctuation marks, and non-ASCII characters with a '%' followed by two hexadecimal digits. urldecode(), on the other hand, is used to decode the data encoded by urlencode(). It decodes the '%' followed by two hexadecimal digits back into its original character.
