cubrid_pconnect — Open a persistent connection to a CUBRID server
$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'.
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.
Connection identifier, when process is successful.
FALSE
, when process is unsuccessful.
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 );
?>
