Establishes a persistent connection to a FrontBase server.

<span class="function"><strong>fbsql_pconnect()</strong></span> acts very much like

<span class="function"><a href="fbsql_connect.html" class="function">fbsql_connect()</a></span> with two major differences:

<p class="para">
|
|
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.
|
|
</p>
|
|
<p class="para">
|
|
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.
|
|
</p>
|
|
<p class="para">
|
|
This type of links is therefore called 'persistent'.
