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'.
