Why does this code (below) run out of memory? It queries
test_table for all rows, all fields and sorts them by the numeric
'contract' field. It then iterates through the rows, and tallies
the number of rows per contract.

Still, an inner and outer loop don't really seem necessary here, as
you're spinning through one set of data, there doesn't seem a need to
run through it that way. A more traditional method is to do something

Hmmm.. Try this..
for($i=0; $i$num_rows; $i++){
$c = mysql_result($result,$i,contract);
echo sprintf( |%13d |%7d |\n, $c, $i );
mysql_free_result($c); //Free the memory with this.
}
or this..
for($i=0; $i$num_rows; $i++){
$c = mysql_result($result,$i,contract);
Here is a link for researching.
