What's a secure alternative to using a MySQL password on the command line?

Benjamin asked:

We have a PHP command-line script to version a database.
We run this script whenever a developer has added a new database patch.

The script runs the patch with the MySQL command-line:

system('mysql --user=xxx --password=xxx < patch.sql');

However, MySQL 5.6 now issues the following warning:

Warning: Using a password on the command line interface can be insecure

Which is obviously true, but might or might not be a problem for the user.

  • What’s the secure alternative then?
  • Alternatively, is it possible to disable this warning?

Please note that I don’t want to have to rely on an external password file.

My answer:


If your PHP script already has an open database connection, why don’t you just use mysqli_multi_query() to import the .sql file? If the syntax of the .sql file is valid, of course…
