Thanks Richard and all responses. That was the best PHP and HTML debug I've learned so far. I always find it is difficult to debug html and JS when doing PHP program. I can debug C/C++ using gdb well but no idea what the tools can be used for browser debug. Anyway, the problem has been resolved. It turns out it was an authorisation issue. My web server requests a log in at beggin, although I can see every pages and download other data and image files, somehow it cannot download the mp3 file. As soon as I remove the login, it works fine. Appreciate all of your helps and responses. Cheers. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I am sure you have many ways to play an mp3 file, that was not what I was asking for. My intention is to learn and understand the PHP and HTML program, and to resolve problems.

Re: [PHP] Browser could not get mp3 files from http site
Thanks Dan and Ash. I've tried object tag, it crashed my firefox. The audio.php file generates a simple following html. You need media player plugin to test it. The web server http://www.myweb.com/audio.php is my home server. Let me further discribe the problems, it is not the embed tag problem, it is the source in the embed tag does not download to the browser (In fact, I've tried the object tag as Ash suggested, the object tag crashed firefox): (1) If I open following audio.html directly from "Open File" file:///home/webserver/audio.html, the embed tag works just fine, the audio can play. The /home/webserver is the directory where all applications audio.php and audio.mp3 are stored. (2) If I open from http://www.myweb.com/audio.php, the audio.mp3 does not download to firefox. Nothing is played. Thanks.

Yes, I'll indeed use the socket connection which will be the minimum process delays and overheads I can get. In option 2 you responsed: > System V message queues are intended for just that; IPC = Inter Process > Communication. The delays and overheads in message queue (in my option 2) may be smaller than the socket, but I guess that might require the external C server to be compiled with the PHP module as they are totally seperated.

I was saying PHP web application is stateless, not the PHP. You are right, it would take more efforts to use the share a single socket. It is not an option. Anyway, thanks for all your responses and suggestions. It was good suggestion to use SOAP and Web services, but we have very small latency requirement, I have already worried about the delay in the lower level of socket, it will be evern more processing delays for useing SOAP and Web services. I'll keep eye on that option if our processing delay requirement can be altered. Thank you. Kind Regards,.

I am not certain if the msg_send / msg_receive in PHP can talk to the external C program msg_send / msg_receive as PHP and external C program are in different processes, different memory spaces.

Let me first describe the requirement more: The C program is a major business server which accesses the database, exchanges information to other remote servers and it has many other background tasks running concurrently for doing monitor, statistic report, real time update data, etc. The PHP web application connects to the C program to get data and information and to display on user's web browser. I know socket works between the PHP and external C server, but there are many concerns depends on different implementations: (a) A simple way is if for every PHP request, it opens socket, sends a request and gets a response from the C server then closes the socket. It should work, but I am not sure: (i) if the open / close socket per request will cause delays and performance issues. (ii) What is the maximum number concurrent requests in a PHP web application? Will the maximum socket number / or port number (up to 2^16) be a bottleneck for large number of concurrent requests (hundred and thousands)? (b) If for all PHP requests share only one socket to connect to the external C server, I am not sure if the PHP is able to do multiplex responses for each request as the PHP is stateless. Thank you.
