Hello....
I would like to know the performance of pg_fetch_array. Cosider the code:
$query = "select * from foo";
$result = pg_query( $db, $query );
while ($row = pg_fetch_array($result))
{
$a = $row["a"];
$b = $row["b"];
$c = $row["c"];
$d = $row["d"];
}
Does php need to read database everytime when pg_fetch_array is executed in
the while loop or all the rows have been in the memory after pg_query?
If read database is needed, is there any method to copy all the rows into
memory by using other command? (because I have a application which needs
large amount database update/retrieval and I wish the performance of the
overall applications run faster.)
or other method you would like to recommend in order to make the faster
response time?
Thank you in advance.
