Example #1 MysqlndUhConnection::getErrorNumber() example

<?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($ret, true));
   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...
