Exporting Structure and Data (Backup) - Mastering phpMyAdmin 3.1 for Effective MySQL Management - page 123

Here is an example taken from the Export page:

CSV
This format is understood by a lot of programs, and you may find it useful for
exchanging data. Note that it is a data-only format—no SQL structure here.

The available options are:

• Fields terminated by : We put a comma here, which means that a comma will

be placed after each field.
Fields enclosed by • : We place an enclosing character here (like the quote) to

ensure that a field containing the terminating character (comma) is not taken
for two fields.
Fields escaped by • : If the export generator finds the Fields enclosed by

character inside a field, the Fields escaped by character will be placed before
it in order to protect it. For example, "John \"The Great\" Smith" .
