urlencode — convert non-alphanumerics to URL encoded escape sequences


string urlencode(url);
string url;


Returns the string url but with the following conversions:

  • Letters and digits are left unchanged.
  • Spaces are converted to "+" characters.
  • All other characters are converted to URL escape codes of the form "%xx", where xx is the ASCII character code in hexidecimal form.

This function is most commonly used for forming URLs with arbitrary data, as shown in the example below.
