Just add a \ s to your regex, like this:
[a-zA-Z \ d \ s]
I also changed the 0-9 by \ d just to show what you can do.

Try to do this:
$string = 'palavra com espaço 123';
if (preg_match("/[\sa-zA-Z0-9]+?$/i", $string)) {
echo '<pre>'; print_r($string); echo '</pre>';
}
Adding a \s that matches any whitespace character.
