Simply loop through the results and do whatever you want to do with
them, and don't put them into an array at all.

Hey all,
I read on php.net about resources, the type
returned from mysql_query(), and was trying locate
the best way to get the result set back from a
query into an array.
Is simply looping through the result set with
mysql_fetch_assoc() the common way to do this?

I don't buy "zero doesn't count". But again, this is getting into serious
math. It should be good enough to say 0-4 = 0, 5-9 = 10, but if you don't keep
strict high precision throughout the whole process and round at every step,
things are going to be off no matter what. It's just a matter of

For downward rounding, you'd always want to use floor() and use ceil() for
rounding up. round() rounds up on a 5, down on a 4 and below.
Example:
echo round(141.074, 2); // 141.07
echo round(141.065, 2); // 141.07
I thought round() (or maybe it was a rounding function in another language or
echo is slightly faster than print and it takes multiple arguments so
instead of:
echo '' . $test . '';
you can do
echo '' , $test , '';
which should be faster, and I say 'should' just because as print should be
slower because it has to go into the trouble of setting up a return value,

You could use addslashes():

Or, the code you mentioned below, could be rewritten like:

or
str_replace('"','\"',$code);
And if you're doing it for a MySQL query call, then you want to use

Yes, echo is faster than print. I would suggest echo over print since it
is shorter and faster :)
