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!
