mysqlnd_ms_get_last_used_connection
Returns an array which describes the last used connection
Description
array mysqlnd_ms_get_last_used_connection(
mixed connection);
Returns an array which describes the last used connection from the plugins connection pool currently
pointed to by the user connection handle. If using the plugin, a user connection handle represents a
pool of database connections. It is not possible to tell from the user connection handles properties to
which database server from the pool the user connection handle points.
The function can be used to debug or monitor PECL mysqlnd_ms.
Parameters
connection
A MySQL connection handle obtained from any of the connect
functions of the
mysqli , mysql or PDO_MYSQL extensions.
Return Values
FALSE
on error. Otherwise, an array which describes the connection used to execute the last
statement on.
Array which describes the connection.
Property Description Version
scheme
Connection scheme. Either
tcp://host:port
or
unix://
host:socket
. If you want to distinguish connections from each
other use a combination of
scheme
and
thread_id
as a unique key.
Neither
scheme
nor
thread_id
alone are sufficient to distinguish
two connections from each other. Two servers may assign the same
thread_id
to two different connections. Thus, connections in the
pool may have the same
thread_id
. Also, do not rely on uniqueness
of
scheme
in a pool. Your QA engineers may use the same MySQL
server instance for two distinct logical roles and add it multiple times to
the pool. This hack is used, for example, in the test suite.
Since 1.1.0.
host

with TCP/IP connections. It is empty with Unix domain or Windows

port

The value is empty for TCP/IP connections. Since 1.1.2.
