Mysqli results memory usage
- by Poe
Why is the memory consumption in this query continuing to rise as the internal pointer progresses through loop? How to make this more efficient and lean?
$link = mysqli_connect(...);
$result = mysqli_query($link,$query); // 403,268 rows in result set
while ($row = mysqli_fetch_row($result))
{
// print time, (get memory usage), -- row number
}
mysqli_free_result();
mysqli_close($link);
