Example #1 MysqlndUhConnection::changeUser() example
<?php
class proxy extends MysqlndUhConnection {
/* Hook mysqlnd's connection::change_user call */
public function changeUser($res, $user, $passwd, $db, $silent, $passwd_len) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::changeUser($res, $user, $passwd, $db, $silent, $passwd_len);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
return $ret;
}
}
/* Install proxy/hooks to be used with all future mysqlnd connection */
mysqlnd_uh_set_connection_proxy(new proxy());
/* Create mysqli connection which is using the mysqlnd library */
$mysqli = new mysqli("localhost", "root", "", "test");
/* Example of a user API call which triggers the hooked mysqlnd call */
var_dump($mysqli->change_user("root", "bar", "test"));
?>
The above example will output:
proxy::changeUser(array ( 0 => NULL, 1 => 'root', 2 => 'bar', 3 => 'test', 4 => false, 5 => 3, )) proxy::changeUser returns false bool(false)
