In a php project, if we get the requirement , we usually start design and database. But the data entry procedure is very hard. In this case PhpMyadmin is a good comfort.
Here is another tool from phpguru.org , MySQL Table Editor. Using this library you can make your database table editable from your php code.
You can :

  1. Select the table to be displayed
  2. decide which column should be hidden
  3. Whether a column should be editable or not
  4. Add advanced searching option
  5. Download the table as csv format
  6. Add pagination
  7. Set alias display name for your column
