Why are these not a match

[NZ_Kiwis]

 echo $Tail . ' ' .$Rego . "<BR>";
            if (trim($Tail) === trim($Rego)){
                echo 'correct';
                $TailCheck = 1;
            } else {
                echo var_dump($Tail);
            }

My output is this

VH-ABC VH-ABF
C:\wamp64\www\home\get-sector.php:88:string 'VH-ABC' (length=6)

Isn't it obvious that they are different?
