Re: [PHP] FW: looking for two remote functions
Can you maybe explain why you want the exact size on the disk in blocks??
do you care if it differs 1KB?? what are you planning to write, the actual
filesize on the disk can only differ 1 block with real filesize, and so if
the blocksize is 1024bytes, it differes a max of 1024bytes...
And btw, the size it takes on your server in blocks might be different then
the size it takes on the server's disk...
I'm not totally sure how a hdd works, but i know it is split up in blocks,
and so you need to know the blocksize on the partition you are going to
place the file, using different filesystems on 1 system can mean that a file
is bigger/smaller on the same system.
So the way to calculate the block filesize would be by getting the real
filesize, and then round it until $filesize%$blocksize == 0
So, in PHP code it would like this.
$blocksize = 1024; // Default on Ext2/3 i believe
$filesize = filesize(http://server.com/file.rar;);
while($filesize%$blocksize != 0)
{
$filesize += 1;
}
I'm not sure if it's the size you were looking for, but keep in mind that it
depends on the block size. So different filesystems use different block
size.

It has to be on the machine from which the pages are being served.
There have been several workable suggestions for different
possibilities. I think it would help if you gave the context for this.
Are these pages on your own web site? Are you downloading pages from
third-party web sites using the browser? Are you using the command line
to download pages from other servers?
Here is a script which will get the headers for any file you can
download from the web:
?php
$fp = fsockopen(www.example.org, 80, $errno, $errstr, 30);
if (!$fp) {
echo $errstr ($errno)br /\n;
} else {
$out = HEAD http://www.example.org/any_page.html / HTTP/1.1\r\n;
$out .= Host: www.example.org\r\n;
$out .= Connection: Close\r\n\r\n;
fwrite($fp, $out);
$header = ;
while (!feof($fp)) {
$header .= fgets($fp, 256);
}
fclose($fp);
echo $header;
}
?
In response you will get the headers:
HTTP/1.1 200 OK
Date: Sun, 11 Mar 2007 14:57:54 GMT
Server: Apache/2.0.51 (Fedora)
Last-Modified: Sun, 11 Mar 2007 13:00:03 GMT
ETag: 10eb0036-4d1-3c2bbac0
Accept-Ranges: bytes
Content-Length: 1233
Connection: close
Content-Type: text/plain; charset=UTF-8
This includes the content-length, which is what you want. This script
will download only the headers.
You will not get a content-length headers for php files, since they are
in effect scripts and their length is not know in advance. The same
holds true for files which contain SSI.

I don't know if there are faster ways, but you could open a socket to the
host on port 80, get the file, and only read the header where it says
content-length: 400 for example, then you know the file is 400bytes when you
download it.
something like:
$socket = fsockopen($host,$port);
$size = 0;
while($size == 0)
{
$line = fgets($socket);
if(strlen($line) = 17)
{
if(substr(strtolower($line),0,14) == content-length)
{
$size = substr($line,16)

Now your remote file size is in $size.

This question has come up before, and out of curiosity I did some
checking. If you use firefox liveheaders, it turns out that the file
size on the linux file system is exactly the size shown in the
content-length header. This is also the same size as returned by php's
filesize() and by the php stat() in its size element. Linux reports the
actual file size, not the storage size, which you can get by asking to
see the number of blocks used to store the file (ls -ls).
I wrote a small perl script which returns the bytes read when a file is
read from the disk and it, too, agrees with the filesize and header
sizes. In Windows, the actual filesize is also returned by filesize and
stat, not the size on disk (filesize uses stat). Also, in the PHP
manual, the fread example uses filesize to set the number of bytes to read:
|contents = fread($handle, filesize($filename));
|The point of this is to read in the exact number of bytes for the file,
not the entire size of the file's storage on disk which would contain
garbage. This has to work on both windows and linux.
Here's the perl script:
use strict;
use Fcntl;
sysopen (FH, index.htm, O_RDONLY);
my $buffer;
my $len = sysread(FH, $buffer, 8192,0);
print $len,\n;
If you are really anxious about size you can exec out to this script and
get the file size.
