Array small question

[shror]

I need help in a small problem,
I have created a registration form and I want my users not leave the
username empty or even enter any number of spaces because sometimes I
found that the users enter some space hits in the username and the
form is submitted, so I created an array and tried to enter the spaces
but I don't know how to make my code reject any spaces whatever their
number and I failed doing this, and what I did was that I entered in
an array the user-names I reserve for later use and space, two-spaces,
three-spaces, four-spaces, ........... but I was exhausted so please
could you tell me how to solve this and do it in a professional way.

http://www.php.net/trim

//trim whitespace surrounding the string
$string = trim($string);
//check for empty string
if(!empty($string)){
//do your thing
} else {
echo 'Please enter a username';
}
