1) More people use PHP in this way than do web-style.

2) Why would he do that? If you were writing a perl script or an awk

But if you have permissions set up correctly, it's easier to just have
the pound-bang at the top of your file.

But that's going to spit out a bunch of HTML; all the OP wants is a
"Hello World" program.

PHP is almost always installed in user $PATH. There's no need for the
/pathtophp/.

What specific bash errors? You need to
1) Make sure you've got the PHP path right (type "type php").
2) Make sure you're script has execute permissions (type
"chmod +x myscript.php").
3) Add a newline to that print statement; your output could be
buffered, and it's more portable to add a newline to guarantee
that it displays. (That, and without a newline your prompt will
should up right after it on the same line.)
