4096 is the number of bytes fgets() will get, but the fgets()
call is inside a while loop which keeps running until the 'filepointer'
(as denoted by the handle $dataFile) in question has reached the end of the
given file. so if 4096 is not big enough the loop merely grabs another 4096
bytes until its grabbed it all.
so actually you have a handy bit of code which will allow you to 'eat' through
massive files without the requirement of being able to store the
whole file in memory.
Is there a way to detect the filesize and insert a value for 4096?
filesize()
$buffer = fgets($dataFile, $filesize);
Is this what it is for?

[PHP] Re: fopen
Hi,
yes, there could be some problem with your code. But it depends on what
are you trying to archieve.
If you are trying to put whole file to database, there is no reason to
use fgets function. Just use $buffer=file_get_contents($filename); and
put the buffer into SQL. No reason to read it line by line using fgets.
The whole file will end in memory in the SQL section, so it doesn't
matter ho you read it.
If you want to process huge file line by line, it's really good idea to
not put whole file to memory (using file_get_contents) but to read it
line by line using fgets, process every line and forgot it. The file
could be very large and you still need only very small memory amount.
And there can be problem you are saying.
What if there is some line longer than 4096 bytes (or some bigger
limit)?? You can solve it simply using code like this:
$dataFile = fopen( $filename, "r" ) ;
$buffer = "";
while (!feof($dataFile)) {
$buffer .= fgets($dataFile, 4096);
if (strstr($buffer, "\n") === false && !feof($dataFile)) {
// long line
continue;
}
echo $buffer;
$buffer = "";
}

[PHP] Perl style
Hi guys
I would like to convert this ..
$tmparray = split(',', $csvstring);
$element5 = $tmparray[5];
. to something like this:
$element5 = (split(',', $csvstring))[5];
. but I just can't find the correct syntax. It is Perl style - i know, but I
just love this syntax. :-)
Does anyonw know the correct syntax?

The syntax is correct in your first example, AFAIK the PERL syntax you
describe cannot be done straight up in PHP unless you write a function to
handle it. You could always write a PHP extension.

[PHP] MySql connection error on win XP for script that works on Freebsd 5.3
I have just installed MySql on Win XP and am attempting to run a php script to create some databases. The script works fine on FreeBSD 5.3 running mysql-client-5.0.11 and mysql-server-5.0.11. MySQL has been installed on windows XP using a download of mysql-5.0.13-rc-win32.zip. Test.php reports php version 4.3.1.0 and is installed with ZendStudio which I am currently testing on win XP as I cannot yet get any version of Zend later than 3.x to run on FreeBSD. The username for mysql is 10 chars with a password of 8 chars and is able to login successfully from the command line. However when attempting to login via the script I get the following error: "Error while connecting to MySQL: Client does not support authentication protocol requested by server; consider upgrading MySQL client." I have searched the mysql website and located an article which shows reference to this error indicating that the client may need to be upgraded but as I am using the mysql-5.0.13-rc-win32.zip package I am cautious about assuming that that is the actual cause. I am curious whether it is something to do with the php version. Does anyone know how I can fix this?

and this one:

'the rest' involves find your substring's beginning and ending
offset and then
using those values to 'splice' the new substring (aka password)
into the file/stream,
I can visualize how ot do it but have never actually needed to do
something like
that ... I would say the compress/decompress is the easier part

Re: [PHP] regex and global vars problem
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.

Re: [PHP] regex and global vars problem
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.

which is 'better' (for what), preg_*() or ereg[i]*()?

I am not recieving any error codes, just an empty var.
Sample output:

As you can see $mac3 is a valid example of a h/w address where $mac1 &

OK, thanks for that. I've rewritten your function below in much cleaner

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).
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}\$#";

}

There may be a backwards-compatible function written in 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. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Decompress a zlib'd string in PHP
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

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:

Okay, now we are getting somewhere.
dcomzlib is, most likely, not the same as zlib.
I tried the below with gzinflate and with gzuncompress.
Both give errors:
gzinflate(): data error
gzuncompress(): data error
And this pretty much clinches it, mostly, assuming you passed in the
right data.

And this is just "data" with not much we can do to guess about its

(also the only one in English) was to:

where somebody pretty much tells you how to decompress this, I think.
