<?php
class proxy extends MysqlndUhConnection {
public function selectDb($res, $database) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::selectDb($res, $database);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysqli = new mysqli("localhost", "root", "", "test");
$mysqli->select_db("mysql");
?>
The above example will output:
proxy::selectDb(array (
0 => NULL,
1 => 'mysql',
))
proxy::selectDb returns true
