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 20.340.
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,
