exec(ls -al)

[Anon]

Hi, i use following code

exec("ls -al",$output);
while (list($key,$val)=each($output)) {
echo basename($val)."<br>";
}

Somehow the last $val prints twice

Why is this happening?

is your $output empty before you call exec?

Yes.

Even if a value was assignred to it,
it will still give me the same result.
