PDO Prepared Inserts multiple rows in single query

Question

I am currently using this type of SQL on MySQL to insert multiple rows of values in one single query:

INSERT INTO `tbl` (`key1`,`key2`) VALUES (\'r1v1\',\'r1         


        

Answer 1

Since it has not been suggested yet, I'm pretty sure LOAD DATA INFILE is still the fastest way to load data as it disables indexing, inserts all data, and then re-enables the indexes - all in a single request.

Saving the data as a csv should be fairly trivial keeping in mind fputcsv. MyISAM is fastest, but you still get big performance in InnoDB. There are other disadvantages, though so I would go this route if you are inserting a lot of data, and not bother with under 100 rows.
