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

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 (<span class="function"><a href="sybase_close.html" class="function">sybase_close()</a></span> will not
|
|
close links established by <span class="function"><strong>sybase_pconnect()</strong></span>).
|
|
</p>
|
|
<p class="para">
|
|
This type of links is therefore called 'persistent'.

This allow you to make separate connections in the same script to the
|
|
same database. This may come handy when you have started a transaction
|
|
in your current connection, and you need to be able to do a separate
|
|
query which cannot be performed inside this transaction.
