How to download a sql database file

If you only have one mysql user for accessing all your databases, restoring directly from a sql file does not have much more security improvement over using phpmyadmin. Using a hosting package with the ability of managing mysql users is a good solution. Otherwise you have to verify an uploaded sql file before restoring from this file. In the following you will find three suggestions on how you could verify an uploaded file.

All of the suggestions build on the assumption that you use a sql file, which has been generated on the server. Create a digital signature at download and validate the signature at upload. For sure, you have to upload the digital signature together with the sql. Store a hash value of the downloaded sql on the server and check for existents of this hash value at upload. Using an ID for the sql files might be helpful. Save the whole sql files on the server and only allow restores from these files.

It doesn't handle NULL. It doesn't delimit table names or column names properly. It doesn't handle character sets. And worst of all, this code appends the all its output into a single string , which will exceed PHP's memory limit unless you database is trivially small. It's a very bad solution.
