SYBASE_PCONNECT(3) SYBASE_PCONNECT(3)
sybase_pconnect - Open persistent Sybase connection
SYNOPSIS
resource sybase_pconnect ([string $servername], [string $username], [string $password], [string $charset], [string $appname])
DESCRIPTION
sybase_pconnect(3) acts very much like sybase_connect(3) 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(3) will not close links established by sybase_pconnect(3)).
This type of links is therefore called 'persistent'.
PARAMETERS
o $servername
- The servername argument has to be a valid servername that is defined in the 'interfaces' file.
o $username
- Sybase user name
o $password
- Password associated with $username.
o $charset
- Specifies the charset for the connection
o $appname
- Specifies an appname for the Sybase connection. This allow you to make separate connections in the same script to the same data-
base. This may come handy when you have started a transaction in your current connection, and you need to be able to do a separate
query which cannot be performed inside this transaction.
RETURN VALUES
Returns a positive Sybase persistent link identifier on success, or FALSE on error.
