PHP Manual: Open a new connection to the MySQL server

Description

public bool MysqlndUhConnection::connect ( mysqlnd_connection $connection , string $host , string $use" , string $password , string $database , int $port , string $socket , int $mysql_flags )

Open a new connection to the MySQL server.

Parameters

connection: Mysqlnd connection handle. Do not modify!
host: Can be either a host name or an IP address. Passing the NULL value or the string "localhost" to this parameter, the local host is assumed. When possible, pipes will be used instead of the TCP/IP protocol.
user: The MySQL user name.
password: If not provided or NULL, the MySQL server will attempt to authenticate the user against those user records which have no password only. This allows one username to be used with different permissions (depending on if a password as provided or not).
database: If provided will specify the default database to be used when performing queries.
port: Specifies the port number to attempt to connect to the MySQL server.
socket: Specifies the socket or named pipe that should be used. If NULL, mysqlnd will default to /tmp/mysql.sock.
mysql_flags: Connection options.

Return Values

Returns TRUE on success. Otherwise, returns FALSE

Examples

Example #1 MysqlndUhConnection::connect example


<?php
class proxy extends MysqlndUhConnection {
 public function connect($res, $host, $user, $passwd, $db, $port, $socket, $mysql_flags) {
   printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
   $ret = parent::connect($res, $host, $user, $passwd, $db, $port, $socket, $mysql_flags);
   printf("%s returns %s\n", __METHOD__, var_export($ret, true));
   return $ret;
 }
}
mysqlnd_uh_set_connection_proxy(new proxy());

$mysqli = new mysqli("localhost", "root", "", "test");
?>

The above example will output:

proxy::connect(array (
  0 => NULL,
  1 => 'localhost',
  2 => 'root',
  3 => '',
  4 => 'test',
  5 => 3306,
  6 => NULL,
  7 => 131072,
))
proxy::connect returns true
