Hi,
I have a problem with date function.
$gen_pos = mktime(0,0,1,10,25,2009);
$d1 = date(Y-m-d, $gen_pos); // 2009-10-25
$d2 = date(Y-m-d, $gen_pos + (1*24*60*60)); // 2009-10-25
$d3 = date(Y-m-d, $gen_pos + (2*24*60*60)); // 2009-10-26
$d4 = date(Y-m-d, $gen_pos + (3*24*60*60));
Hi,
i would ask what is the best method for random select from database. I
have table with 20k items..
- If i use ,,select * from table order by rand() limit 3, the query
took 0.0524 sec ... its slightly enough
- but if i generate rand id and then i use ,,select where id
thx it looks good

For large tables, I generally create a static_rand column, and pre-populated
it with random numbers and create an index on it.
Then, after using up the records, I have application logic to reset those
records (and only those records) to new

Try to work with error_reporting set to E_ALL ;)
