Name:
Category: Strings
Body:

/*
This function takes a string and returns an array with words (delimited by spaces), also taking into account quotes,
 doublequotes and backslashes (for escaping stuff);
So the string
 cp 'my file' to "Judy's file"
becomes
 Array
  [0] => cp
  [1] => my file
  [2] => to
  [3] => Judy's file

This is version 2, using preg_match to jump over chunks of type 'other' characters.
Also added backticks.
