Php sha1 method returns only 2 binary char

I have written this code below.

<?php $str = "hafeezullah";    echo "TRUE - Raw 20 character binary format: ".sha1($str, TRUE)."<br>";    ?>  

I read the tutorials that if in the sha1 method TRUE(parameter) is passed then it generates 20 binary characters, but when I practically implemented it then it generated only 2 binary characters. What is the problem?

OUTPUT: TRUE - Raw 20 character binary format: �E
