Like this?

<?php
$test=array("te st me", "testme", "test_me", "test89+");
foreach($test as $x) {
if(preg_match('/^[A-Za-z0-9_]*$/',$x))
print "$x was OK.\n";
else
print "$x wasn't OK.\n"
}
?>

if(preg_match('/^\w+$/',$x))

Does the same thing except shorter, and doesn't accept empty usernames.

if (preg_match('/^(\w|\s)+$/', $x))


'\s' defines a space. The (...|...) will select either (\w or \s) so you
cover both.
