To decompress the string you'll want gzuncompress. More on zlib & php:
http://ca.php.net/manual/en/ref.zlib.php
The on-line manual is your friend :-).

Just to show I am not a total leech, I did consult the manual before
I posted the question :)
The compressor in the file data says: dcomzlib
I tried the below with gzinflate and with gzuncompress.
Both give errors:
gzinflate(): data error
gzuncompress(): data error
The below is the copy/pasted hex of the compressed movie header in
the Quicktime Movie File
FYI ,I did not compress the string myself...it is compressed
automatically when a Quicktime movie is exported.

If I remove pack, I get the error:
gzuncompress(): data error
$uncompressed = gzuncompress($the_string);
echo $uncompressed;
in my hex editor, the movie header contains:
ftypqt qt Pmoov Hcmov dcomzlib 4cmvd
From the Quicktime Docs, 'dcomzlib' is supposed to be the
compression method for the below string:

And this pretty much clinches it, mostly, assuming you passed in the

Hi Richard :)
Looks like all he did was change a couple of atoms names...BEFORE
the compressed movie header stuff :(
All in all.... is all pretty basic stuff.
I am more interested in what comes AFTER dcomzlib.
Quicktime automatically decompressed the movie header when it plays a
file, so there has to be way to decompress it?
As far as legality, I am hacking my own files :)
Ultimately, I want to write a password variable into the Quicktime file
My hope is that all movie variables are also compressed with
dcomzlib...as they are no where to be found by looking at the hex :(
If I can find the variables, then I can rewrite them :)
I know several members of the Quicktime Engineering team, and no one
has made a peep.
But, they will not tell me the answer either ;)
Maybe they are waiting to sue me the moment I figure it out ;)
Here is a 'test' movie I created:
These two examples are the SAME file...One has a compressed movie
header. The other is uncompressed
So...one has dcomzlib, and one is not
Uncompressed Movie Header:

Hi,
On the MPlayer samples FTP, there is an example of a MOV file that
is presumably "protected" in:
ftp://ftp.mplayerhq.hu/MPlayer/samples/MOV/protected_mov/
Has anyone looked closely at the file? I was trying to figure out
what was
protected about it. The first 32 bytes are:
00 00 22 B6 68 24 2E 6D 00 00 22 AE 62 30 72 29 ..".h$.m..".b0r)
00 00 00 0C 64 63 6F 6D 7A 6C 69 62 00 00 22 9A ....dcomzlib..".
The "dcomzlib" tag looks familiar. I had a hunch and changed a few
of the
bytes to:
00 00 22 B6 6D 6F 6F 76 00 00 22 AE 63 6D 6F 76 ..".moov..".cmov
00 00 00 0C 64 63 6F 6D 7A 6C 69 62 00 00 22 9A ....dcomzlib..".
And then I was able to parse the file with a custom QT parser I
assembled:

I am having a problem with a couple of function I have written to check

Um I did actually, but I will re-interate the problem with more detail.
the vars $mac1, $mac2, & $mac3 are to get passed to the chk_mac()
function which determines if it is a valid hex representation of a h/w
address, if it does not meet the criteria of having a ":" separating
every two characters it then passes the var to the fix_mac() function
which attempts to fix the string or h/w address by either replacing any
"-" with a ":" or to break the h/w address up and insert a ":" every two
characters. I also believe this is the one you should be playing with
as the last post I added a new regex which wasn't working.
Any help is appreciated.

OK, you've told us what your code does. Now can you explain what the
problem is? "A new regex which wasn't working" is a bit vague.
* Does it throw an error?
- If so, can we have the error message?
* Does it mark invalid strings as valid?
- Or vice versa?
Just posting a pile of code with an explanation of what it does and
leaving the rest of us to figure out what the problem is, is not helping
us to help you.

The code I just showed you is supposed to do the following, the
chk_mac() returns a true or false on the vars $mac1, $mac2 and $mac3.
$mac3 is the only var that should not be thrown into the fix_mac()
function which is working correctly. The problem is when $mac1 and
$mac2 get put into the fix_mac() function nothing is being returned.
I am not recieving any error codes, just an empty var.
Sample output:
00aa11bb22cc converted to
00-aa-11-bb-22-cc converted to
00:aa:11:bb:22:cc is valid.
As you can see $mac3 is a valid example of a h/w address where $mac1 &
$mac2 were returned from the fix_mac() function as an empty string.

OK, thanks for that. I've rewritten your function below in much cleaner
code. Some of the situations you've used regexps in, string functions
would work fine. They're also much faster.
The below function works fine in my testing. I removed the special-case
for a valid MAC address at the start since your regexp was throwing
errors and there was no need since you already checked if it was valid
with chk_mac() (which by the way should return true or false, not 1 or
0, but meh).
<?php
function fix_mac( $mac ) {
if( eregi(
"^[0-9A-Fa-f]{2}\-" .
"[0-9A-Fa-f]{2}\-" .
"[0-9A-Fa-f]{2}\-" .
"[0-9A-Fa-f]{2}\-" .
"[0-9A-Fa-f]{2}\-" .
"[0-9A-Fa-f]{2}$",
$mac
) ) {
$mac_final = str_replace( '-', ':', $mac );
} else if( eregi( "^[0-9A-Fa-f]{12}$", $mac ) ) {
$mac_array = str_split( $mac, 2 );
$mac_final = implode( ':', $mac_array );
} else {
return false;
}
echo "MAC: $mac_final";
return $mac_final;
}
?>

gonna jump on your thread there Jasper, I would
like to comment on your function and ask you a question:
which is 'better' (for what), preg_*() or ereg[i]*()?

this string concatenation looks a bit naff.
although on second thoughts I can see why you did it this way.
down to personal choice :-).
the use of double quotes means strictly speaking
you should be escaping the backslash and dollar sign (and the
parentheseses?) although i would recommend single quotes.
I would have used preg_match(), something like
(I'm using double quotes because of the php -r '' btw :-):
php -r '
$d = "([0-9A-Fa-f]{2})";
$q = "{$d}[\\-:]?";
$re = "#^{$q}{$q}{$q}{$q}{$q}{$d}\$#";
foreach(array("900030ABAB0C",
"90-00-30-AB-AB-0C",
"90:00:30:AB:AB:0C",
"90-00-30:AB:AB-0C",
"90:JJ:30:AB:AB-0C") as $str) {
$matches = array();
if (preg_match($re, $str, $matches)) {
$mac = join(":", array_slice($matches, 1));
echo "good mac: $mac\n";
} else {
echo "bad mac: $str\n";
}
}
// and as a function:
function getMAC($str)
{
static $re;
if (!isset($re)) {
$d = "([0-9A-Fa-f]{2})"; $q = "{$d}[\\-:]?";
$re = "#^{$q}{$q}{$q}{$q}{$q}{$d}\$#";
}
return (preg_match($re, $str, $matches)) ? join(":", array_slice($matches,
1)) : null;
}
foreach(array("900030ABAB0C",
"90-00-30-AB-AB-0C",
"90:00:30:AB:AB:0C",
"90-00-30:AB:AB-0C",
"90:JJ:30:AB:AB-0C") as $str) {
if ($mac = getMAC($str)) {
echo "good mac: $mac\n";
} else {
echo "bad mac: $str\n";
}
}
'
$mac
) ) {
$mac_final = str_replace( '-', ':', $mac );
} else if( eregi( "^[0-9A-Fa-f]{12}$", $mac ) ) {
$mac_array = str_split( $mac, 2 );
$mac_final = implode( ':', $mac_array );

Did you read the second comment on the str_split manual page? I suspect
you're using php4.

The (PHP 5) notion near the top of this page:
http://php.net/str_split
was intended to inform you that it was added in, and is available only
in, PHP 5 and later.
There may be a backwards-compatible function written in <?php ... ?>
code in PECL or PEAR.
The User-Contributed notes at the above link may also have a function
to duplicate functionality in earlier versions.
Or you could upgrade, of course.
And, of course, in future you'll know to check the version info in the
manual so you'll know right off what's going on. It's a VERY nice
feature of the on-line manual, I must say.

Hi
In Install.text for php 5.0.5 on Page 3:
Heading Manual Installation Steps
"Previous editions of the manual suggest moving various ini and DLL files into
your SYSTEM folder......we advise remove all these files (like php.ini and
PHP related DLLs from the Windows System folder..."
While some files in the Windows folder are clearly php related in that they
are of the form
php*.*
other files are not so easily distinguished.
I wonder if someone has a list of the files that should be deleted bearing in
mind I have just removed an installation of php 4.3.10 and php 5.0.5. I would
like to make sure that the windows system32 folder is clean! It would be nice
if such a list was added to install.txt
thanks

If all else fails, you could just download the PHP .zip files and open
them up, without un-zipping, and see the list of files.
Errrm, not in that wack wizard mode, but classic mode of WinZip.

Thanks for that -- I have decided to upgrade to 5.0.5 -
