[PHP] Re: Multiple Threads?

2002-04-14 Thread Richard Creech 

Hello All,
IF you are using mySQL database then the php manual indicates you can run multiple 
connections. Presumably you could execute several web queries at the same time, each 
with its own connection. I haven't tried such, but the manual suggests it is possible:

http://www.php.net/manual/en/function.mysql-connect.php

If a second call is made to mysql_connect() with the same arguments, no new link will 
be established, but instead, the link identifier of the already opened link will be 
returned. The new_link parameter modifies this behavior and makes mysql_connect() 
always open a new link, even if mysql_connect() was called before with the same 
parameters. 
Note: The new_link parameter became available in PHP 4.2.0 
 


Kind Regards,

Richard Creech

if, for instance, you had to get information from UPS, FedEx, and the
USPS about shipping rates to display on a page. If you had to query them
one at a time, the delay would be unacceptable. However, with that perl
module, you could query them all at the same time, making it much
faster.
 
Does anyone know if such a thing exists for PHP?

Won't work for web connections, because it waits for each connection to
complete before running the next one.
