Hi there Ariane,
As I understand it. CRUD is just a mechanism by which you use PHP (or
the language of your choice) to drive data table manipulation (CRUD =
Create/Read/Update/Delete).
Many mySQL clients (e.g., sqlYog) enable you to build queries using a
graphical interface with the option of formatting the output as a set
of statements ready to be embedded into PHP; is that what you're
looking for?
I don't use graphical query generators myself - I find it's much
quicker to write mysql_query() and mysqli_multi_query() stuff directly
within a PHP page in a PHP IDE... but you then have to know your
database structure reasonably well (or have a db browser open at the
same time).
Cheers
