URL encoding converts characters into a format that can be safely transmitted over the Internet.

URL - Universal Resource Locator

Web browsers request pages from web servers by using a URL.
The URL is the address of a web page like: http://www.1000sourcecodes.com.

URL Encoding

URLs can only be sent over the Internet using the ASCII character-set.
Since URLs often contains characters outside the ASCII set, the URL has to be converted. URL encoding converts the URL into a valid ASCII format.
URL encoding replaces unsafe ASCII characters with "%" followed by two hexadecimal digits corresponding to the character values in the ISO-8859-1 character-set.

URLs cannot contain spaces. URL encoding normally replaces a space with a + sign.

URL Encoding Functions

In JavaScript, PHP, and ASP there are functions that can be used to URL encode a string.
In JavaScript you can use the encodeURI() function. PHP has the rawurlencode() function and ASP has the Server.URLEncode() function.
Note: The JavaScript function encodes space as %20.
