MysqlndUhConnection::connect

(PECL mysqlnd-uh >= 1.0.0-alpha)

MysqlndUhConnection::connect — Open a new connection to the MySQL server

说明

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

Open a new connection to the MySQL server.

参数

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.

返回值

Returns TRUE on success. Otherwise, returns FALSE

范例

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");
?>

以上例程会输出:

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