Interesting, I don't have any numerical benchmarks, but I saw a
performance benefit moving my result set into an array.
My case may have been extreme, I was creating a table 350 rows by 350
columns, several megabytes of output, and I found that building the
output directly from the query too
Always found the same myself on large datasets and when working with
high traffic sites; but cant replicate in a non-live environment or with
simple grinder style tests; so just follow the procedure as standard
practise in all my code now - likewise with dropping keep alive times on
apache servers

Subject: [PHP] Close MySQL Result
I think I am a dork.
How do I close a MySQL result set to free memory?
Given something like this:
$gsql = Select * from resources where queryName = 'Production';;
$myresult = mysql_query($gsql) or die

you'll also find a performance upgrade if you load all sql
results in to
an array and close up the query / free the results before
working on them.
query
for() {
$results[] = $row;
}
close stuff
work on
