Associative arrays

[Jawelin]

... cram .... RAM ... :greedy:

So it would be more efficient go back & forth through the recordset instead of loading data into Ram ?
Isn't it too heavy to mySQL engine ?

I should compare new users data with old ones.
If I had 'N' news (let's say 10 at a time) and 'T' total old users (let's say +3000...), the complexity of the check should be:
N*T = 30.000 seeks on DB !!!!
:noid:

Any idea ?

Thanks.

P.S.: and what about using mysql_fetch_array() or mysql_fetch_row() just after the seek ? Either which ?
