例1 MysqlndUhConnection::stmtInit() example
<?php
class proxy extends MysqlndUhConnection {
public function stmtInit($res) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
var_dump($res);
$ret = parent::stmtInit($res);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
var_dump($ret);
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysqli = new mysqli("localhost", "root", "", "test");
$stmt = $mysqli->prepare("SELECT 1 AS _one FROM DUAL");
$stmt->execute();
$one = NULL;
$stmt->bind_result($one);
