urlencode — URL-encodes


syntax


string urlencode ( string $str )

This function is convenient when encoding a string to be used in a query part of a URL, as a convenient way to pass variables to the next page.


str - The string to be encoded.


Returns a string in which all non-alphanumeric characters except -_. have been replaced with a percent (%) sign followed by two hex digits and spaces encoded as plus (+) signs. It is encoded the same way that the posted data from a WWW form is encoded, that is the same way as in application/x-www-form-urlencoded media type. This differs from the » RFC 3986 encoding (see rawurlencode()) in that for historical reasons, spaces are encoded as plus (+) signs.
