phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as a
single database. To accomplish the latter you'll need a properly set up MySQL
user who can read/write only the desired database. It's up to you to look up
the appropriate part in the MySQL manual.

Currently phpMyAdmin can:

* browse and drop databases, tables, views, fields and indexes
* create, copy, drop, rename and alter databases, tables, fields and indexes
* maintenance server, databases and tables, with proposals on server
configuration
* execute, edit and bookmark any SQL-statement, even batch-queries
* load text files into tables
* create^1 and read dumps of tables
* export^1 data to various formats: CSV, XML, PDF, ISO/IEC 26300 -
OpenDocument Text and Spreadsheet, Word, Excel and L^AT[E]X formats
* import data and MySQL structures from Microsoft Excel and OpenDocument
spreadsheets, as well as XML, CSV, and SQL files
* administer multiple servers
* manage MySQL users and privileges
* check referential integrity in MyISAM tables
* using Query-by-example (QBE), create complex queries automatically
connecting required tables
* create PDF graphics of your Database layout
* search globally in a database or a subset of it
* transform stored data into any format using a set of predefined functions,
like displaying BLOB-data as image or download-link
* track changes on databases, tables and views
* support InnoDB tables and foreign keys (see FAQ 3.6)
* support mysqli, the improved MySQL extension (see FAQ 1.17)
* communicate in 57 different languages
* synchronize two databases residing on the same as well as remote servers
(see FAQ 9.1)
