ibase_pconnect — Open a persistent connection to an InterBase database
说明
ibase_pconnect
([ string $database
[, string $username
[, string $password
[, string $charset
[, int $buffers
[, int $dialect
[, string $role
[, int $sync
]]]]]]]] ) : resource
Opens a persistent connection to an InterBase database.
ibase_pconnect() acts very much like ibase_connect() with two major differences.
First, when connecting, the function will first try to find a (persistent) link that's already opened with the same parameters. If one is found, an identifier for it will be returned instead of opening a new connection.
Second, the connection to the InterBase server will not be closed when the execution of the script ends. Instead, the link will remain open for future use (ibase_close() will not close links established by ibase_pconnect()). This type of link is therefore called 'persistent'.
