I am having a problem with my localhost. It is the lamp setup with nothing modified running on Ubuntu Hardy. Html files seem to work fine but when I try to get anything php related to run I get the following error message:

Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in /var/www/tester.php on line 2

I can not figure out why this error is occuring as my code appears fine to me. Here is my code:

Code:
<?php 
echo “Hello World”;
?>
I am relatively new to apache and Ubuntu together but I have a decent amount of experience with Windows and apache so if there is any editing to the httdp.conf file that I should do please be precise!
