Opens a persistent connection to an InterBase database.
</p>
<p class="para">
<span class="function"><strong>ibase_pconnect()</strong></span> acts very much like
<span class="function"><a href="function.ibase-connect.html" class="function">ibase_connect()</a></span> with two major differences.
</p>
<p class="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.
</p>
<p class="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 (<span class="function"><a href="function.ibase-close.html" class="function">ibase_close()</a></span> will not close links
established by <span class="function"><strong>ibase_pconnect()</strong></span>). This type of link is
therefore called 'persistent'.
