Oops there... functions that take strings as an argument should be provided strings, which are quoted (preferably double quotes, however PHP does handle single quotes)

use

exec("ping localhost");

if you need the output, consider using

passthru ("/somewhere/bin/blah etc etc");

Actually I'm suprised exec(ping) actually works.

if you turn on error reporting, php will probably say
"undifed constant LS, assumed to be 'ls'"
or something like that.
Effectively PHP replaces the constant with a string equal to the name of the constant.

so
exec(ls);
is turned into
exec('ls');

then,
exec(ls al);

won't work, because if "al" is seen as a constant, it is completely out of place there.
