Beschreibung
Procedural style
bool maxdb_real_connect ( resource $link [, string $hostname [, string $username [, string $passwd [, string $dbname [, int $port [, string $socket ]]]]]] )
Object oriented style (method)
maxdb
bool real_connect ([ string $hostname [, string $username [, string $passwd [, string $dbname [, int $port [, 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.
Rückgabewerte
Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.
Beispiele
Beispiel #1 Object oriented style
<?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();
?>Beispiel #2 Procedural style
<?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);
?>Das oben gezeigte Beispiel erzeugteine ähnliche Ausgabe wie:
Connection: localhost <...>
