mysql_info -- Get information about the most recent query

## Description

string mysql_info ( [resource link_identifier])

mysql_info() returns detailed information about the last query using the given link_identifier. If link_identifier isn't specified, the last opened link is assumed.

mysql_info() returns a string for all statements listed below. For everything else, it returns `FALSE`. The string format depends on the given statement.

例 1. Relevant MySQL Statements
    INSERT INTO ... SELECT ...
    String format: Records: 23 Duplicates: 0 Warnings: 0
    INSERT INTO ... VALUES (...),(...),(...)...
    String format: Records: 37 Duplicates: 0 Warnings: 0
