<?php
class proxy extends MysqlndUhConnection {
 public function 
getErrorNumber($res) {
   
printf("%s(%s)\n"__METHOD__var_export(func_get_args(), true));
   
$ret parent::getErrorNumber($res);
   
printf("%s returns %s\n"__METHOD__var_export($rettrue));
   return 
$ret;
 }
}
mysqlnd_uh_set_connection_proxy(new proxy());

printf("connect...\n");
$mysqli = new mysqli("localhost""root""""test");
printf("query...\n");
$mysqli->query("PLEASE_LET_THIS_BE_INVALID_SQL");
printf("errno...\n");
var_dump($mysqli->errno);
printf("close...\n");
$mysqli->close();
?>

The above example will output:

 connect... proxy::getErrorNumber(array ( 0 => NULL, )) proxy::getErrorNumber returns 0 query... errno... proxy::getErrorNumber(array ( 0 => NULL, )) proxy::getErrorNumber returns 1064 int(1064) close...
