您如何将数据库中的枚举与您的 PHP 代码同步？

Question

A db with several hundred tables will usually have more then few enums/sets defined in it.
How do you synchronize you PHP code with the enum values, to avoid using string literals in your code (which we all know it just seems easier, but in the long run causes stupid bugs).
The only good solution I can think of is using, during the build of the project, a process which will generate constants for all the enums in the DB, or, create and compile a PHP extension with those values.
Any different, better solutions out there?

Answer 1

As Plato would say: either PHP and SQL are independent, or SQL is generated from PHP, or PHP is generated from SQL, or both are generated from the same source.

The first is usually unacceptable if there's a lot of changes happening, but otherwise quite stable.

The second is what happens with a lof of recent solutions that manage your SQL from the PHP side (and gracefully handle schema changes from the PHP side as well). This means your mad SQL ninja skills might be useless and frustrating .

The third is what you suggest. It's fine as long as you can manage the "generated during build" part without stepping on the toes of your source control system and your package system. Having a clean build system helps (which is somewhat unusual in PHP).

The fourth involves adapting an existing database modeling tool to generate both the SQL schema and the PHP code. This way, you would simply work with the tool once every two weeks, generate both PHP and SQL, and commit the result. Adapting the tool, however, can be quite nasty (then again, you can try to look for an XML export and work from there).
