Sockets - Streaming to a Browser and Timing Out

[markwod]

Hi,

 

  I'm new to the PHP world. I've put together a simple script (below) with I intend to connect a server which sends out a stream of ASCII (I've a client in C++ with all works well). For now I just want it to read 250 bytes from the stream then somehow update a field on a brwoser.

 

Which has lead me to these two questions:

 

1) Whist debugging, the script does connect and read bytes ok. But when I stop debugging PHP is still keeping the connection live, so when the script runs again it fails to work. I've found a few time out methods, all of which see to have now effect.

 

2) Presumably using some javascript or other. can anyone suggest a resource which will give me an idea on how to this data back to the browser (as it comes in) and update the field without user interaction.

 

Many thanks

 

Mark
