<?
$cmd = "ls dir/transactions1/junk.170_*";
$tst = @exec($cmd);
?>

This produces the following message before the heading is displayed:

dir/transactions1/junk.170_*: No such file or directory

ls writes to stderr, which isn't piped by popen(), which
results in this behavior.  There's nothing you can do about
it at the PHP level.

You can, however, ask the shell to do the job for you,
by doing something like:

$tst = @exec("ls dir/transactions1/junk.170_* 2> /dev/null");

which tells sh to redirect all stderr output to /dev/null.
