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'.
Host name or IP address of CUBRID CAS server.
Port number of CUBRID CAS server (BROKER_PORT configured in $CUBRID/conf/cubrid_broker.conf).
Name of database.
User name for the database.
User password.
Connection identifier, when process is successful.
FALSE
, when process is unsuccessful.
<?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:
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
