# cubrid_pconnect

Open a persistent connection to a CUBRID server

### Description

resource cubrid_pconnect ( string `$host` , int `$port` , string `$dbname` [, string `$userid` [, string `$passwd` ]] )

Establishes a persistent connection to a CUBRID server.

cubrid_pconnect acts very much like cubrid_connect with two major differences.

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.

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 (cubrid_close or cubrid_disconnect will not close links established by cubrid_pconnect).

This type of link is therefore called 'persistent'.

### Parameters

`host`

  Host name or IP address of CUBRID CAS server.

`port`

  Port number of CUBRID CAS server (BROKER_PORT configured in $CUBRID/conf/cubrid_broker.conf).

`dbname`

  Name of database.

`userid`

  User name for the database.

`passwd`

  User password.

### Return Values

Connection identifier, when process is successful.

`FALSE`, when process is unsuccessful.

### Examples

Example #1 cubrid_connect example

`<?php
printf("%-30s %s\n", "CUBRID PHP Version:", cubrid_version());
printf("\n");
$conn = cubrid_pconnect("localhost", 33000, "demodb", "dba");
if (!$conn) {
die('Connect Error ('. cubrid_error_code() .')' . cubrid_error_msg());
}
$db_params = cubrid_get_db_parameter($conn);
while (list($param_name, $param_value) = each($db_params)) {
printf("%-30s %s\n", $param_name, $param_value);
}
printf("\n");
$server_info = cubrid_get_server_info($conn);
$client_info = cubrid_get_client_info();
printf("%-30s %s\n", "Server Info:", $server_info);
printf("%-30s %s\n", "Client Info:", $client_info);
printf("\n");
$charset = cubrid_get_charset($conn);
printf("%-30s %s\n", "CUBRID Charset:", $charset);
cubrid_disconnect($conn);
?>`

The above example will output:
