RE: How to make binary strings useful?

["Jerry Miller" <gamphd@xxxxxxxxxxxxx>]

Here's the code (with the domain name removed)
that doesn't work, "despite" the poor documentation
of the variable types:

<?
        $dir = "/home/<domain_name>/www/binary/";
        $dh = opendir ($dir);
        do
        {
                $file = readdir ($dh);
        }
        while (!strncmp ($file, ".", 1));
        $filename = sprintf ("%s%s", $dir, $file);
        $fh = fopen ($filename, "r");
        $cont = fread ($fh, 4);
        echo "file:<BR>";
        echo $filename;
        echo "<BR>cont:<BR>";
        printf ("%02x %02x %02x %02x", $cont{0}, $cont{1}, $cont{2},
$cont{3});
        fclose ($fh);
        closedir ($dh);
?>

Here's the output of "od -c glance_date" up to the fourth byte:

0000000 177   E   L   F

All four bytes are non-zero!
