checking strings

[marconi8]

sorry people for that basic question but i cannot find out in this little problem for me

function checkSTR($s)
{
$s=strip_tags($s);
$s=ltrim(rtrim($s));
return $s;
}

i'am trying to use empty with function using, and i get parse error which i cannot find

if (!empty(checkSTR($HTTP_POST_VARS['login'])))
{
}

on this last if i get parse error, hm what's wrong

thanks

[man]empty/man only takes variables ("This is a variable. Is there anything in it?"). Things returned from functions don't count as variables (things returned from functions get put into variables).
If you're wanting to see if the result of trim(strip_tags($s)) is an empty string, look to see if it =="" or not.
