This really needs some explanation
I found this on the web:
<?php echo `whoami`; ?>
with it there was the comment "the direction of those single-quotes matters"
(WHY ?)
and it works....
But this (_*FROM THE PHP MANUAL***_ * - exec()* executes the given
/command/ ) does not,
COPIED AND PASTED:
|<?php
// outputs the username that owns the running php/httpd process
// (on a system with the "whoami" executable in the path)
echo exec('whoami');
?> |
What is going on here?
And I often find such discrepancies in examples - and some wonder why I
seem to be so stupid... and don't know the fundamentals... :-\
