[PHP] handling file upload (OT not exactly PHP)
Hello , Need to do handle a file upload done via http POST. I can read the content length and from POST and get the contents. But, how do I get the exact file ?? Eg. suppose for uploading a .doc file I could see that it sends the font type and other parameters also.. I am not sure how does it will matter when I am extracting the exact file from the POST request . Again, how would I extract the exact file ?? Would appreciate any pointers or someone giving me some headstart . Thanks and Regards, -Saswat -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Need help: change a string in a file
Richard, Thanks for the answer. I understand that I can't do it the way I wanted . I have changed my design. Thanks ALL who answered. -Saswat On Apr 7, 2005 8:18 AM, Richard Lynch [EMAIL PROTECTED] wrote: On Wed, April 6, 2005 10:07 am, Saswat Praharaj said: I need some help in searching string in a file. My requirement is to search the string,append something to the string . Write the string back to the file without changing other parts of the file. e.g Suppose I have the following string in a file Set-Cookie: T_COOKIE=127.0.0.1-saswat-9; path=/ The fixed string is Set-Cookie: T_COOKIE=and rest of the string is variable. I would like to change the string 127.0.0.1-saswat-9 to say 127.0.0.1-saswat-9-1234 Problem is, that's *MORE* bytes than are already there. You can't just smush a few more bytes in. You will *HAVE* to write out a new file. But you can read in only the first couple hundred bytes until you find your Set-Cookie: T_COOKIE, and then you write out the stuff before that, write out your new data, then read/write the whole rest of the file. You may also want to consider using, say, awk or sed or whatever from http://php.net/exec -- I don't expect them to be that much faster than PHP, but what do I know? My constraint is : I don't want to read the whole file into a buffer and work on that buffer as the file can be very large , sometimes more than 10 mb. My advantage is : I know that I will get the search string in first 200 bytes of the file , so I just need to read 200 bytes,play with that and write it back (overwriting the first 200 bytes with new 200 some bytes) .. If it's really 200 bytes for 200 bytes, yeah, fopen(..., 'r+') will work. But if you can't squeeze your bytes into the same space as is already there, you can't do that. You might also be able, for the future, to start using: 127.0.0.1-saswat-9-000 and then you'd be able to replace up to and get back something you can easily read/write/format to be meaningful. -- 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

[PHP] newbie:changing variable to type resource
Hi All, I am new to PHP, stuck with a problem and need your help. I would like to change a variable to type resource. I searched in php.net and in google but did not find anything helpful. Now , why I would like to do that... I am writing a socket application which will accept connection from browser,receive data and write the data sent by browser into another open socket.Receive data from the open socket and write it back to the browser. When there are more than one client(browser) connecting to my program ,I am saving the connection information (socket ID)for browser connections in a plain text file. I intend to retrive the socket ID information and do a socket_write(..) with socket ID as the first parameter, but I am getting an error that I cant convert any type to a resource type. Is there any workaround ?? Is it going to help me if I use session information ? I am not using apache. I may be wrongly designing the program. Would appreciate all your suggestion and help.

Re: [PHP] newbie:changing variable to type resource
Richard, Thanks for the quick reply. Here is what I am trying to do : I am trying to tunnel some http packets from the browser to a PC which is inside a private network/firewall. The PC in the pvt. netwok sends a request to my server at regular interval. When the browser wants to send some packets to the PC (which it can't without opening a port in the firewall), it sends the packets to my program and my program tunnels those packets in the response to the request messeges coming from the PC inside the firewall. I am able to do it when there is only one PC and one browser tries to access it by storing the socket ID of the browser connection in a temporary variable in my program ,but I need some kind of mechanism to store socket IDs for connections coming from multiple browsers. Without which I can't distinguish between different connections.

The design just maybe might be fine in theory, but in practice... A socket connection can't be shared across PHP instances, I don't think. Certainly not by writing the resource into a text file. You *MIGHT* be able to write the resource into shared memory http://php.net/shmop but I doubt that will work at all, and even if it does, having two programs reading/writing the same socket resource at one time sounds like a recipie for disaster. Why do you want to share this socket across two PHP programs? What exactly are you doing? I suspect that the design is not right, even in theory, but can't be sure. -- 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
