[PHP] php output fills apache buffer for clients with slow internet connections
Dear Ladies and Gentlemen,
the last couple of days I browsed the internet for the answer of a
questions which seems to be a common problem ... but found now real
solution:
I would like to serve large files (100MB) to my clients using php:
while (moreDataAvailable()) {
printChunk(getChunk());
flush();
waitToReduceBandwidth();
}
Normally that works fine. However when the client has a slower internet
connection than I set using waitToReduceBandwidth() the output of the
php script builds up in the buffer of Apache. ... and the Apache process
reaches a couple of hundred MBytes ...
A solution would be to reduce the bandwidth so that is even lower than
the slowest connection ... but then clients with faster connections
would complain ...
Therefore (finally) here come the questions:
Is there a way to control the output speed of the php script according
to the actual download speed between the browser and the server?
Or is there a way to monitor the memory usage of the apache process (to
slow down the data output when it increases)?
Or is writing my own socket to act as web server a solution (is it
possible to monitor the connection speed this way)?
Or what should I do else?
Any hints are welcome, cheers
Martin

Re: [PHP] php output fills apache buffer for clients with slow internet
Try apaches' SendBufferSize config directive SendBufferSize sets the size of the TCP send buffer. Increasing the size would help only within high-speed networks to speed up the connection. However the 'slow-connection' clients are not in the same network. Thus increasing the TCP send buffer could even result in an increased number of tropped TCP packages ... Thanks (I was not aware of that directive) Martin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Re user Identifying
The problem you are describing is implemented in a quite amazing GPL shop. You might want to have a look: www.oscommerce.org Regards Martin Peter Goggin wrote: I did not make my request for information clear. The two scenarios which I have to cover: 1. The user registers as a customer with the site. In this case the shopping basket and items can be attached to the customer Id. and the shopping basket made available across sessions. The shopping basket is created when the first item is added. It is closed when the final order is placed. I have already coded this and it works satisfactorily. 2. The user does not register. Instead the process is to add items to a shopping basket, which is then converted to an order or discarded at the end of the session. How do I identify shopping baskets belonging to different concurrent users? Should I include the session Id in the record, use cookies or what? Is the php session Id a unique ID ?

[PHP] WebTV vs PHP
Has anybody expirienced troubles with clients using some sort of WebTV? I got a bug report saying - sbdy using WebTV has problems with our sites. We are using pure PHP - no JAVA, no JAVAScript ...
