cubrid_pconnect

(PECL CUBRID >= 8.3.1)

cubrid_pconnect — Open a persistent connection to a CUBRID server

说明

cubrid_pconnect(
    string $host,
    int $port,
    string $dbname,
    string $userid = ?,
    string $passwd = ?
): resource

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'.

参数

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.

返回值

Connection identifier, when process is successful, 或者在失败时返回 false.

范例

示例 #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);
?>

以上例程会输出：
