sybase_pconnect ( [string servername [, string username [, string password [, string charset [, string appname]]]]])
Returns a positive Sybase persistent link identifier on success,
or FALSE on error.
sybase_pconnect() acts very much like
sybase_connect() with two major differences.
First, when connecting, the function would first try to find a
(persistent) link that's already open with the same host,
username and password. If one is found, an identifier for it
will be returned instead of opening a new connection.
Second, the connection to the SQL server will not be closed when
the execution of the script ends. Instead, the link will remain
open for future use (sybase_close() will not
close links established by sybase_pconnect()()).
This type of links is therefore called 'persistent'.
See also sybase_connect().

The servername specified in sybase_connect and sybase_pconnect is solved
locally on the PHP3 server host, which should be configured with the
appropriate Sybase client configuration. This includes setting the
environment variables for the account that runs the PHP3 extension, i.e. if
it runs as a Web server extension, it must be configured in the user
account that runs the Web server. You may setup at least the SYBASE
environment, and add $SYBASE/bin within the user's path that runs the Web
server. Standard installations of Sybase clients include setting up either
a $SYBASE/interfaces file under Unix, or %SYBASE%\ini\sql.ini under
Windows. This file contains local aliasnames for the referenced server
names. These names may be different than that really used on the host that
run the Sybase SQL Server. What is important is that this Sybase client
configuration file will specify the location of the SQL Server, i.e. the
network protocol to use, and if it's through TCP/IP, the host name or IP
address of the Sybase SQL Server host, and its listener port number. Newer
versions of Sybase includes the option to setup the interfaces or SQL.INI
file with a single server entry, with will be a Sybase naming service. If
this is used, the Sybase OpenClient libraries will connect to this naming
service, if the SERVER name specified can't be solved locally. This naming
service will provide the SQL Server location for the specified SERVER name
you use in the sybase_connect or sybase_pconnect function calls, allowinf
naming resolution on sites that want to have a centralized administration
of multiple Sybase OpenServer servers, including gateways to other SQL
servers such as OpenServer compatible gateways to Oracle or Informix
servers. But if you want faster accesses to your Sybase SQL server used by
your PHP3 scripts, you should configure the host which runs the PHP3
extension so that servernames can be solved locally. All you need is to add
server entries in your interfaces or SQL.INI Sybase OpenClient
configuration file.
