length of string driving me mad

[pyro13]

if (strlen($_POST['Text']) < 20)
 $lessthantwenty = $_POST['Text']

although if my post string is more than 18 characters it wont follow through.... rather i will need:

if (strlen($_POST['Text']) < 22)
 $lessthantwenty = $_POST['Text']

instead to follow through with a 20 character string... is there a reason for this? where are my extra 2 characters coming from?

Clean your string...

if (strlen(trim($_POST['Text'])) < 20)

the strlen function counts white spaces as characters, so it may be because of that.

also you might want to use a <= to make the expression more accurate
