[PHP] Supress error message to apache log?

[Michael A. Peters]

I have the following php function-

function doclink ($documentdir, $rpmname, $doc_file) {
        $string="rpm -qd $rpmname |head -1 |sed s?\"$documentdir\"?\"\"? |cut -d\"/\" 
-f2";
        $rpm_installed=exec($string);
        $DOC_ABSOLUTE="$documentdir/$rpm_installed";
        if (file_exists("$DOC_ABSOLUTE/$doc_file")) {
                if (is_link("$rpmname")) {
                unlink("$rpmname");
                 }
                symlink("$DOC_ABSOLUTE", "$rpmname");
                return "$rpmname/$doc_file";
        } else {
                return "failed";
        }
}

later its used when creating a page of documentation links for the user, like this-

$mysqldoc=doclink($docdir, "MySQL", "manual_toc.html");
if (strstr($mysqldoc,"failed")) {
        echo "<!-- could not locate MySQL documentation -->\n";
} else {
        echo "<P><font face=$font color=$color size=$size><A href=\"$mysqldoc\">MySQL 
Documentation</A></font>\n";
}

Works beautifully, problem is- if the rpm isn't installed that's querried in the 
doclink function, the error message rpm puts out is sent to the apache error.log. I 
don't want that.

Is there a way to supress the error message for that exec call?

Thanks
