PHP implements text data import into SQL SERVER

PHP to import text files to MySQL we often encounter, but if it is imported to SQL Server and how to operate it, the following will give you to share my operation method, the sense of efficiency is also good, recommended to everyone here.

My test is supported by Csv,sql,txt

In fact, other formats are possible, but I can't use them.

The speed is almost 10,000 per second.
