This function is much like
<span class="function"><a href="function.odbc-connect.html" class="function">odbc_connect()</a></span>, except that the connection is
not really closed when the script has finished. Future requests
for a connection with the same <em><code class="parameter">dsn</code></em>,
<em><code class="parameter">user</code></em>, <em><code class="parameter">password</code></em>
combination (via <span class="function"><a href="function.odbc-connect.html" class="function">odbc_connect()</a></span> and
<span class="function"><strong>odbc_pconnect()</strong></span>) can reuse the persistent
connection.
