getSession — Connect to a MySQL server
Description
$uri
) : mysql_xdevapi\SessionConnects to the MySQL server.
Parameters
-
uri
-
The URI to the MySQL server, such as mysqlx://user:password@host.
URI format:
scheme://[user[:[password]]@]target[:port][?attribute1=value1&attribute2=value2...
-
scheme: required, the connection protocol
In mysql_xdevapi it is always 'mysqlx' (for X Protocol)
-
user: optional, the MySQL user account for authentication
-
password: optional, the MySQL user's password for authentication
-
target: required, the server instance the connection refers to:
* TCP connection (host name, IPv4 address, or IPv6 address)
* Unix socket path (local file path)
* Windows named-pipe (local file path)
-
port: optional, network port of MySQL server.
by default port for X Protocol is 33060
-
?attribute=value: this element is optional and specifies a data dictionary that contains different options, including:
-
The auth (authentication mechanism) attribute as it relates to encrypted connections. For additional information, see » Command Options for Encrypted Connections. The following 'auth' values are supported: plain, mysql41, external, and sha256_mem.
-
The connect-timeout attribute affects the connection and not subsequent operations. It is set per connection whether on a single or multiple hosts.
Pass in a positive integer to define the connection timeout in seconds, or pass in 0 (zero) to disable the timeout (infinite). Not defining connect-timeout uses the default value of 10.
Related, the MYSQLX_CONNECTION_TIMEOUT (timeout in seconds) and MYSQLX_TEST_CONNECTION_TIMEOUT (used while running tests) environment variables can be set and used instead of connect-timeout in the URI. The connect-timeout URI option has precedence over these environment variables.

Example #1 URI examples
mysqlx://foobar
mysqlx://root@localhost?socket=%2Ftmp%2Fmysqld.sock%2F
mysqlx://foo:bar@localhost:33060
mysqlx://foo:bar@localhost:33160?ssl-mode=disabled
mysqlx://foo:bar@localhost:33260?ssl-mode=required
mysqlx://foo:bar@localhost:33360?ssl-mode=required&auth=mysql41
mysqlx://foo:bar@(/path/to/socket)
mysqlx://foo:bar@(/path/to/socket)?auth=sha256_mem
mysqlx://foo:bar@[localhost:33060, 127.0.0.1:33061]
mysqlx://foobar?ssl-ca=(/path/to/ca.pem)&ssl-crl=(/path/to/crl.pem)
mysqlx://foo:bar@[localhost:33060, 127.0.0.1:33061]?ssl-mode=disabled
mysqlx://foo:bar@localhost:33160/?connect-timeout=0
mysqlx://foo:bar@localhost:33160/?connect-timeout=10For related information, see MySQL Shell's » Connecting using a URI String.

Examples
Example #2 mysql_xdevapi\getSession() example
<?php
try {
$session = mysql_xdevapi\getSession("mysqlx://user:password@host");
} catch(Exception $e) {
die("Connection could not be established: " . $e->getMessage());
}
$schemas = $session->getSchemas();
print_r($schemas);
$mysql_version = $session->getServerVersion();
print_r($mysql_version);
var_dump($collection->find("name = 'Alfred'")->execute()->fetchOne());
?>
The above example will output something similar to:
Array ( [0] => mysql_xdevapi\Schema Object ( [name] => helloworld ) [1] => mysql_xdevapi\Schema Object ( [name] => information_schema ) [2] => mysql_xdevapi\Schema Object ( [name] => mysql ) [3] => mysql_xdevapi\Schema Object ( [name] => performance_schema ) [4] => mysql_xdevapi\Schema Object ( [name] => sys ) ) 80012 array(4) { ["_id"]=> string(28) "00005ad66abf0001000400000003" ["age"]=> int(42) ["job"]=> string(7) "Butler" ["name"]=> string(4) "Alfred" }
