试试这个

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli_connect = mysqli_connect("localhost", "root", "", "hexll");

$sqlquery= mysqli_query($mysqli_connect,"select text from mytable where id='1' ");

$row= mysqli_fetch_array($sqlquery, MYSQLI_ASSOC);

echo $row['text'];

你可以得到分配给你的任务 id=1 以以下方式使用pdo

$id = 1;

$sql = "SELECT task FROM your_db_table WHERE `id` = :id ";
$sql ->execute([ 'id' => $id]);
 $task= $sql;

如果你用的是mysqli

$id = 1;

$stmt = $dbConnection->prepare('SELECT task FROM your_db_table WHERE id =?');
$stmt->bind_param('i', $id); // 'i' specifies the variable type => 'integer'

$stmt->execute();

$result = $stmt->get_result();
$text= $result->fetch_assoc();
