this is a very good example of the improvements I hope you'll achieve
with this refactoring.
To run this code, do the following:
- ensure you have a table having two indexes on the same column
- open the db containing this table
- go to Structure for this db
- tick the checkbox for this table name
- in the dropdown, pick "Check table"
You'll see the "Problems with indexes of table" message. To prove that
it's coming from sql.lib.php, make a slight change in one of the
messages output by PMA_getHtmlForIndexesProblems().
Finding the code path that leads to this result is an interesting
exercise that I have done, but I suggest you do it by yourself to gain
experience with the code.
Once you understand this code path, you'll be able to remove one place
where sql.php is included.
