Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

try another thing : 

use \PDO as mysql;
var_dump(method_exists('mysql', '__construct'));
var_dump(method_exists('\PDO', '__construct'));
/*
bool(false)
bool(true)
*/

something wrong no ?
