<para>
|
|
Opens a persistent connection to an InterBase database.
|
|
</para>
|
|
<para>
|
|
<function>ibase_pconnect</function> acts very much like
|
|
<function>ibase_connect</function> with two major differences.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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 (<function>ibase_close</function> will not close links
|
|
established by <function>ibase_pconnect</function>). This type of link is
|
|
therefore called 'persistent'.

The <parameter>database</parameter> argument has to be a valid path to

database file on the server it resides on. If the server is not local,

|
it must be prefixed with either 'hostname:' (TCP/IP), '//hostname/'
|
|
(NetBEUI) or 'hostname@' (IPX/SPX), depending on the connection
|
|
protocol used.
