范例
Example #1 MysqlndUhConnection::nextResult() example
<?php
class proxy extends MysqlndUhConnection {
public function nextResult($res) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::nextResult($res);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysqli = new mysqli("localhost", "root", "", "test");
$mysqli->multi_query("SELECT 1 AS _one; SELECT 2 AS _two");
do {
$res = $mysqli->store_result();
var_dump($res->fetch_assoc());
printf("%s\n", str_repeat("-", 40));
} while ($mysqli->more_results() && $mysqli->next_result());
?>
以上例程会输出:
array(1) { ["_one"]=> string(1) "1" } ---------------------------------------- proxy::nextResult(array ( 0 => NULL, )) proxy::nextResult returns true array(1) { ["_two"]=> string(1) "2" } ----------------------------------------
