urlencode
(PHP 3, PHP 4 )urlencode -- URL-encodes string
Description
string urlencode ( string str)
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 RFC1738 encoding (see rawurlencode()) in that for historical reasons, spaces are encoded as plus (+) signs. This function is convenient when encoding a string to be used in a query part of an URL, as a convenient way to pass variables to the next page:
这个函数好好看看了。
