UrlEncode

(PHP3, PHP4)

UrlEncode---&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; URL-encoded string

Syntax: string urlencode (String str)

Description:

The string of all non-alphanumeric characters, except-_, is represented by a percentage sign (%) followed by two confusing digits, while whitespace is encoded as a positive (+) symbol. This encoding method is the same as that of the WWW form post data, which, unlike the RFC1738 encoding, is encoded as a positive (+) symbol, which is suitable for use in part of the URL of the query and is suitable for passing variables to the next page.

Example:

<?php

Echo ' <a href= ' mycgi?foo= ', UrlEncode ($userinput), ' > ';

?>

Reference: UrlDecode () Rawurlencode () Rawurldecode ()
