here code information omitted.

$servername = "ip:port"; $username = "username"; $password = "password"; $dbname = "db"; $conn = new mysqli($servername, $username, $password, $dbname); if ($conn->connect_error) {     die("connection database failed. please try again. error: " . $conn >connect_error); } $sql = "select id, timestamp posts order timestamp desc limit 1,10;"; $result = $conn->query($sql); $arrays = array(); if ($result->num_rows > 0) {     while($row = $result->fetch_assoc()) {         $arrays[] = $row[id];     } } foreach ($arrays $key => $id) {     $servername = "ip:port";     $username = "username";     $password = "password";     $dbname = "db";     $conn = new mysqli($servername, $username, $password, $dbname);     if ($conn->connect_error) {         die("connection database failed. please try again. error: " . $conn->connect_error);     }        $sql = "select name,timestamp,text posts id=\"" . $id . "\";";     $result = $conn->query($sql);     $arrays = array();     if ($result->num_rows > 0) {         while($row = $result->fetch_assoc()) {             $date = date_create_from_format('y-m-d h:i:s',$row[timestamp]);             $timezone = new datetimezone('america/los_angeles');             $timedate = date_timezone_set($date, $timezone);             $finaltimedate = $timedate->format('y-m-d h:i:s a');             echo "<hr><h4>" . $row[name] . "<span style=\"float:right\">time posted: " . $finaltimedate . "</span></h4><br>";             echo $row[text] . "<br>";         }     } } 

however, when reload page, shows 2 of same, id=0, blog post rather post 0 , 4 (only 2 posts).

if understand question, query should work you.

select id, timestamp table_name order timestamp desc limit 1,10;
