fbsql_pconnect Open a persistent connection to a FrontBase Server


fbsql_pconnect

(PHP 4 >= 4.0.6, PHP 5)

fbsql_pconnectOpen a persistent connection to a FrontBase Server

说明

resource fbsql_pconnect ([ string $hostname = ini_get("fbsql.default_host") [, string $username = ini_get("fbsql.default_user") [, string $password = ini_get("fbsql.default_password") ]]] )

Establishes a persistent connection to a FrontBase server.

To set the server port number, use fbsql_select_db().

fbsql_pconnect() acts very much like fbsql_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.

This type of links is therefore called 'persistent'.

参数

hostname

The server host name.

username

The user name for the connection.

password

The password for the connection.

返回值

Returns a positive FrontBase persistent link identifier on success, or FALSE on error.
