bool maxdb_real_connect ( resource $link [, string $hostname [, string $username [, string $passwd [, string $dbname [, int $port = 0 [, string $socket ]]]]]] )

객체 기반 형식

bool maxdb::real_connect ([ string $hostname [, string $username [, string $passwd [, string $dbname [, int $port = 0 [, string $socket ]]]]]] )

maxdb_real_connect() attempts to establish a connection to a MaxDB database engine running on hostname.

This function differs from maxdb_connect():

maxdb_real_connect() needs a valid resource which has to be created by function maxdb_init()
With function maxdb_options() you can set various options for connection.

예제

Example #1 객체 기반 형식


<?php

/* create a connection object which is not connected */
$maxdb = maxdb_init();

/* set connection options */
$maxdb->options(MAXDB_UNICODE, "FALSE");
$maxdb->options(MAXDB_TIMEOUT, 5);

/* connect to server */
$maxdb->real_connect('localhost', 'MONA', 'RED', 'DEMODB');

/* check connection */
if (maxdb_connect_errno()) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

printf ("Connection: %s\n.", $maxdb->host_info);

$maxdb->close();
?>

Example #2 절차식 형식


<?php

/* create a connection object which is not connected */
$link = maxdb_init();

/* set connection options */
maxdb_options($link, MAXDB_UNICODE, "FALSE");
maxdb_options($link, MAXDB_TIMEOUT, 5);

/* connect to server */
maxdb_real_connect($link, 'localhost', 'MONA', 'RED', 'DEMODB');

/* check connection */
if (maxdb_connect_errno()) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

printf ("Connection: %s\n.", maxdb_get_host_info($link));

maxdb_close($link);
?>

위 예제의 출력 예시:

Connection: localhost <...>
