Returns: A positive FrontBase persistent link
identifier on success, or
FALSE
on error.
fbsql_pconnect()
establishes a connection to a FrontBase server. The following
defaults are assumed for missing optional parameters:
host
= 'localhost',
username
= "_SYSTEM" and
password
= empty password.
fbsql_pconnect()
acts very much like
fbsql_connect()
with two major differences.
To set Frontbase server port number, use
fbsql_select_db()
.
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.
This type of links is therefore called
'persistent'.
