How to save a HTML table in MySQL database - efficient way to do this? [closed]


Problem :

I have a php website with a html table. The user is able to modify each of the contained cells (much like in Excel), e.g. change it's content or font-size. My current approach is to save these cells in a one-to-many relationship: One mysql table for the different tables and one mysql table with the cells. To each "table-object" there are several "cell-objects" assigned. The problem I have at the moment is, that this generates really a lot of db querys (about 2200 when saving or opening one table, one for each cell). I think that this really is too much, isn't it (or at least not good way of practice)?

Can anyone give me a hint, what other way I could achieve this? Or is it ok like this anyway?

Thanks in advance,

Solution :

You could probably collect all the cell data into a multidimensional array of cells split into rows:

$table = array(
    array(0, 1, 2, 3, 4, 5),
    array(0, 1, 2, 3, 4, 5),
    array(0, 1, 2, 3, 4, 5)
);

Then serialize the whole array using PHP serialize() and save it in a single MySQL TEXT field.

When you read from the database, you can just unserialize() the field and it's back to being a normal PHP array which you can loop through and print out the table.
