Example #1 MysqlndUhConnection::listFields() example
<?phpclass proxy extends MysqlndUhConnection { public function listFields($res, $table, $pattern) { printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true)); $ret = parent::listFields($res, $table, $pattern); printf("%s returns %s\n", __METHOD__, var_export($ret, true)); return $ret; }}mysqlnd_uh_set_connection_proxy(new proxy());$mysql = mysql_connect("localhost", "root", "");mysql_select_db("test", $mysql);mysql_query("DROP TABLE IF EXISTS test_a", $mysql);mysql_query("CREATE TABLE test_a(id INT, col1 VARCHAR(255))", $mysql);$res = mysql_list_fields("test", "test_a", $mysql);printf("num_rows = %d\n", mysql_num_rows($res));while ($row = mysql_fetch_assoc($res)) var_dump($row);?>
以上例程会输出:
proxy::listFields(array ( 0 => NULL, 1 => 'test_a', 2 => '', )) proxy::listFields returns NULL num_rows = 0
