It trims ALL leading and trailing spaces, one solution to the problem with explode()include spaces in the
array.

If you have a string which only contains whitespace, then this function cannot strip the whitespace.

how do strip whitespaces in the middle of a string, for instance if a user adds a space between his regin prefix and the rest of his phonenumber?

An example

<?php
$stri = "\nThis string has \ whitespace\n\n\n";
echo trim($stri);
?>

Hope that helps..

If you are trying to take out whitespace from the middle of a string, you need to use a different function, str_replace:

<PRE>str_replace(" ", "", "United Kingdom);</PRE>
