Not that you necessarily *can* run out and buy a 64-bit machine, mind you. yes. especially since each of our front-end webservers would need to be 64-bit to do what i was hoping to do. what I was hoping for was a way to make php use 64-bit integers (or fake it somehow), such as apache2.0.54 does for files of that size.

At least for THIS particular function, you could use exec(du $filename, ...) and then you'd have a string representation of the size, which you could then display or even manipulate with BC_MATH or that other new-fangled arbitrary precision mathematics PHP Module whose name I forget. This is a much less general solution, but may suffice for now. well, it may suffice actually. I'm just not sure of the performance impact of doing this for every file from all our front-end boxes anytime someone does a directory listing. thanks for the answers :-) --dan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Achieving 64-bit integers on 32-bit platforms
Hi Folks This 32-bit limitation is haunting me everywhere I turn. Is it possible with PHP (at compile-time if need be) to make it use large (64-bit) integers? I'm asking because I would like to perform operations on large files, and fillesize($filename) is returning an error, even when I use sprintf(%u, filesize($file)) as per the manual for filesize(). I get: Warning: filesize(): Stat failed for FC4-i386-DVD.iso (errno=75 - Value too large for defined data type) Any thoughts/ideas/suggestions? Thanks!

Re: [PHP] Interesting question re HTTP Ranges and PHP
Hi Chris, a million thanks for the help there. That's what i thought I'd
have to do.
What I'm doing now is inspect the Range header to pull out the start and
end, and then deduce the length, and then using fopen, fseek and fread to
open the file and read from a certain offset for a certain length.
Now I have another dilemma. It's all well and good to use fread() to read
into a variable, and then echo that (or just echo(fread()) ..) but suppose
someone requests from 100-65000 bytes of an ISO file - that's gonna
pretty quickly drag the machine down.
Basically what i'm looking for is something similar to readfile() but with
offset and length support. Any ideas ?? I suspect the answer lies in
streams, but i could be wrong.

I think you will find all header in the $_SERVER array. It is definitely
possible to do what you're wanting, but I'm not sure exactly how simple you
will think it is. Maybe there is some existing code someone has written that
does this sort of thing for you, but I'm not aware of any.
At most, you would just have to parse the Range header yourself to deduce what
byte range to serve.
Also is there a way for PHP to tell apache which response code to
send?
Yeah, this should work:
header('HTTP/1.1 206 Partial Content');
Hope that helps.

[PHP] Interesting question re HTTP Ranges and PHP
Hi folks, I currently have an interesting dilemma - any help is appreciated (if possible, CC directly to [EMAIL PROTECTED] as well as the list). What Ive got is a PHP wrapper script that performs authetication, and uses readfile() to return the requested file. So a user requests /path/to/file, PHP interveins and performs authentication, then does a realfile on /REAL/path/to/file to return the file. What I want is for the PHP script to read ALL the headers for the request (in particular, RANGE headers), and then return the relevant portion of the file. Can this be done fairly simply? Obviously there has to be additional headers returned to the client by the script when it's returning a RANGE response. Also is there a way for PHP to tell apache which response code to send? i.e. in my testing even tho I send a resume code with wget, apache's response is 200 OK, not 206 Partial Content... Any help/advice is appreciated... -Dan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] parse error
Or, another option is to use single-quotes in the HTML: echo(table border='0' width='125' height='27'); That way you can include variables in there if you see fit (since the string itself is still double-quoted), and you don't have to worry about escpaing the double-quotes. -Dan On Thu, 2 Jan 2003, Michael J.
