If you'r using PHP >4 use preg_split. (works also with php 3 >= 3.09)
see http://www.php.net/manual/en/function.preg-split.php for detailed
information.
The split pattern you'd need is:
$sometext2split = "hello world with a lot of whitespaces!";
$myarray = preg_split ("/\s+/",$sometext2split);
you should get
$myarray := ['hello', 'world', 'with', 'a', 'lot', 'of', 'whitespaces!']
But remark: \t (tabs) will also count as whitespace, but not \n and \r. See
docu for more informations
Hope, it helps
best regards
