boolmysqlnd_uh_set_connection_proxyMysqlndUhConnectionconnection_proxymysqlimysqli_connection
Installs a proxy object to hook mysqlnd's connection objects methods.
Once installed, the proxy will be used for all MySQL connections
opened with mysqli,
mysql or
PDO_MYSQL, assuming that the listed
extensions are compiled to use the mysqlnd
library.
The function can be disabled with
mysqlnd_uh.enable.
If mysqlnd_uh.enable
is set to &false; the function will not install the proxy and
always return &true;. Additionally, an error of the
type E_WARNING may be emitted. The error message may
read like PHP Warning: mysqlnd_uh_set_connection_proxy(): (Mysqlnd User Handler)
The plugin has been disabled by setting the configuration parameter mysqlnd_uh.enable = false.
The proxy has not been installed [...].
