I’ve sometimes webservers with very limited access. You probably know those too.
And it’s not always helpful to upload phpMyAdmin – especially if you only need to do basic stuff.

A little helper that I’ve created a long time ago is now “cleaned and ready to be shared”. directmysqldump is a pretty simple helper to dump a whole MySQL-schema. You only have to set your credentials and upload it to your webserver. Then point your browser to the location and you should have an output ready that looks almost like the command-line mysqldump.

But please: Don’t leave the script on the server.
The best thing to do is putting it into a protected folder and have https ready to download your output over a secure channel.
If you leave it unprotected on your server… at least don’t blame me.

And here you can get the directmysqldump-script.

Keep in mind: It’s only a small helper. If you want more functionality, then code it yourself or use a large toolset like phpMyAdmin.

Ein kleiner Hinweis von einem Freund: Ich soll http://www.mysqldumper.de/ empfehlen als “Zwischenschritt” zu phpMyAdmin. Ist hiermit geschehen :-)
