maxdb_real_connect

Opens a connection to a MaxDB server (PECL)
bool maxdb_real_connect ( resource link [, string hostname [, string username [, string passwd [, string dbname [, int port [, string socket]]]]]] )

Procedural style

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.

返回值

如果成功则返回 TRUE,失败则返回 FALSE

Example

例 1038. 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();
?>

例 1039. 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);
?>

The above examples would produce the following output:

Connection: localhost <...>
