objects & arrays

[gingar]

Hi guys,

is it possible to have an array of objects?

would an array of objects load faster than an array by itself?

it seems like i have this piece code that takes ages to load.
It gets info from 2 different xml sources, as well as from my own database, formats the data and displays it onscreen.

The 2 xml sources claim their data is gzipped, so i'm thinking, could be my coding problem. I'm looping through the arrays, and access my database (different tables) a few times within the loop.

Could this be the problem?

What do you mean? An array of objects is an array.

Running database queries in a loop could pose a bottle neck, yes.

Yes, it is possible to have an array of objects. As to the rest, I can't really say how it might or might not improve you performance issues with the limited information at hand. Certainly if you can reduce the number of database queries you may improve performance, but performance issues are often best addressed by doing some performance testing that can provide empirical data as to where the actual performance bottlenecks are, rather than just speculating.

I'm not sure what gzipped content has anything to do with it.

If I understand correctly, through request headers sent from your browser (which will contain info about supporting gzipping), if the server allows gzipping and sees that your browser supports the decompression of gzipping, then the server gzips and sends the content (which gets ungzipped on your browser's end).

Are you saying that you are accessing the database a few times due to gzipping? I'm rather confused.

First, I would add in some timing mechanism and print out the execution times in a couple different places.

I'd suspect the XML parsing to take the most time, depending on the amount of data and which engine you are using to parse it.
