hi I have to create a system of comments within various trhead I performed before and all the while the trhead 'while inside the comment and it works but is really slow and with a large number of threads often gives me timeout error how can I fix the problem?
function commenti($id) {
$query2 = "SELECT * FROM table2 WHERE numid='$id' ORDER BY id ASC";
$result2 = mysqli_query($conn,$query2);
if($result2->num_rows >0)
{
while($row2 = $result2->fetch_array(MYSQLI_ASSOC))
{
$idt2 = $row2['id'];
$testot2 = $row2['testo'];
return $testot2;
}
} else {
echo "No comment";
}
}
$query = "SELECT * FROM table1 where visualizza='1' ORDER BY id DESC";
$result = mysqli_query($conn,$query);
if($result->num_rows >0)
{
while($row = $result->fetch_array(MYSQLI_ASSOC))
{
$id = $row['id'];
$titolo = $row['titolo'];
$testo = commenti($id);
echo "$titolo $testo <br>";
}
}
mysqli_close($conn);
?>
I'm going to assume that you are trying to pull a ton of records. The best way to approach this is to add pagination and only load ~10-20 comments per page. depending on your server
Update:
@OP Basically on first load of the page you load ~10 comments, once they click view more then you load in the next few using ajax. Rinse and repeat.
我以为可以使用联接,但是如果有更多重复项,还可以发表评论
$query = "SELECT * FROM table1 left JOIN table2 ON table1.id = table2.numid where visualizza='1' ORDER BY id DESC";
