SQLite3 :: query语法错误

Question

I have this php code to get data from database

<?php
require_once ("db.php");
$db = new MyDb();

if (isset($_POST['limit']) && isset($_POST['start'])) {

$start = $_POST["start"];
$limit = $_POST["limit"];

$query =<<<EOF
SELECT * FROM questions ORDER BY quiz_id DESC '$start', '$limit';
EOF;

$result = $db->query($query);

while ($row = $result->fetchArray(SQLITE3_ASSOC)) {
  echo 'div class="quesbox">
  <div class="questitle">
      <h2>'.$row["question"].'</h2>
  </div>
  <div class="quesanswer">'.$row["answer"].'</div>
    <div class="quesdatetime"><img src="images/questime.png" alt="export question">'.$row["date"].'</div>
  </div>';
}

}
?>

But each time i run this block of code i get these errors

Warning: SQLite3::query(): Unable to prepare statement: 1, near "'0'": syntax error in C:\xampp\htdocs\xport\searchfetch.php on line 14

Fatal error: Call to a member function fetchArray() on a non-object in C:\xampp\htdocs\xport\searchfetch.php on line 16

I have tried all the possible ways i know to fix the issue by editing the query statement but to no avail. Please where is the issue from. Any help would be appreciated.

Answer 1

You forgot the LIMIT

$query =<<<EOF
SELECT * FROM questions ORDER BY quiz_id DESC LIMIT '$start', '$limit';
EOF;
