ibase_pconnect
(PHP 4, PHP 5)
ibase_pconnect — Open a persistent connection to an InterBase database
Description
resource ibase_pconnect
([ string $database
[, string $username
[, string $password
[, string $charset
[, int $buffers
[, int $dialect
[, string $role
[, int $sync
]]]]]]]] )
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'.
