cubrid_connect — Open a connection to a CUBRID Server

### 説明

cubrid_connect ( string `$host` , int `$port` , string `$dbname` [, string `$userid` [, string `$passwd` [, bool `$new_link` = `FALSE` ]]] ) : resource

The cubrid_connect() function is used to establish the environment for connecting to your server by using your server address, port number, database name, user name, and password. If the user name and password is not given, then the "PUBLIC" connection will be made by default.

### パラメータ

`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. If not given, the default value is "public".

`passwd`

  User password. If not given, the default value is "".

`new_link`

  If a second call is made to cubrid_connect() with the same arguments, no new connection will be established, but instead, the connection identifier of the already opened connection will be returned. The `new_link` parameter modifies this behavior and makes cubrid_connect() always open a new connection, even if cubrid_connect() was called before with the same parameters.

### 返り値

Connection identifier, when process is successful.

`FALSE`, when process is unsuccessful.

### 例

例1 cubrid_connect() example

`<?php
printf("%-30s %s\n", "CUBRID PHP Version:", cubrid_version());
printf("\n");
$conn = cubrid_connect("localhost", 33000, "demodb", "dba");
if (!$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);
?>`
