Php reads the txt file to form an SQL statement and inserts the database code, so that you can easily access your friends /**
* $ SplitChar field delimiter
* $ File data file name
* $ Table database table name
* $ Conn database connection
* $ Name of the column corresponding to fields data
* $ InsertType INSERT operation type, including INSERT and REPLACE
*/

The code is as follows:
