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 $CUBRID/conf/cubrid_broker.conf).
dbname- Name of database.
userid- User name for the database.
passwd- User password.
返回值
Connection identifier, when process is successful.
false, when process is unsuccessful.
范例
Example #1 cubrid_connect() example
<?phpprintf("%-30s %s\n", "CUBRID PHP Version:", cubrid_version());printf("\n");$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：
CUBRID PHP Version: 9.1.0.0001 PARAM_ISOLATION_LEVEL 3 LOCK_TIMEOUT -1 MAX_STRING_LENGTH 1073741823 PARAM_AUTO_COMMIT 1 Server Info: 9.1.0.0212 Client Info: 9.1.0 CUBRID Charset: iso8859-1
