Establishes a persistent connection to a CUBRID server.

</p>

<p class="para">
|
|
<span class="function"><strong>cubrid_pconnect()</strong></span> acts very much like
|
|
<span class="function"><a href="cubrid_connect.html" class="function">cubrid_connect()</a></span> with two major differences.
|
|
</p>
|
|
<p class="para">
|
|
First, when connecting, the function would first try to find a (persistent)
|
|
link that's already open with the same host, port, dbname and userid. 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 (<span class="function"><a href="cubrid_close.html" class="function">cubrid_close()</a></span> or
|
|
<span class="function"><a href="cubrid_disconnect.html" class="function">cubrid_disconnect()</a></span> will not close links established by
|
|
<span class="function"><strong>cubrid_pconnect()</strong></span>).
|
|
</p>
|
|
<p class="para">
|
|
This type of link is therefore called 'persistent'.
