分页有效，但不起作用；Don’不要转到下一页

我在我的网站上添加了分页，一切都很好，但每当我点击下一步，它都会转到同一页面url/dataload2.php？page=0。这是我的php代码，我认为它在计算或循环中有问题，感谢您的帮助。

编辑：添加了更多的代码

    <?php
include 'conn.php';
$num_rec_per_page=2;
if (isset($_GET["page"])) { $page  = $_GET["page"]; } else { $page=1; }; 
$start_from = ($page-1) * $num_rec_per_page; 
$sql = "SELECT * from crewlist ORDER BY name ASC LIMIT $start_from, $num_rec_per_page";
$result = $conn->query($sql);
?>

和

 <?php 
    $sql = "SELECT * FROM crewlist"; 
    $rs_result = mysql_query($sql); //run the query
    $total_records = mysql_num_rows($rs_result);  //count number of records
    $total_pages = ceil($total_records / $num_rec_per_page); 
    echo "<a href='dataload2.php?page=1'>".'|<'."</a> "; // Goto 1st page  
    for ($i=1; $i<=$total_pages; $i++) { 
                echo "<a href='dataload2.php?page=".$i."'>".$i."</a> "; 
    }; 
    echo "<a href='dataload2.php?page=$total_pages'>".'>|'."</a> "; // Goto last page
    ?>

EDIT：更新语法

 <?php 
$sql = "SELECT * FROM crewlist"; 
$rs_result = mysqli_query($sql); //run the query
$total_records = mysqli_num_rows($rs_result);  //count number of records
$total_pages = ceil($total_records / $num_rec_per_page); 
echo "<a href='dataload2.php?page=1'>".'|<'."</a> "; // Goto 1st page  
for ($i=1; $i<=$total_pages; $i++) { 
            echo "<a href='dataload2.php?page=".$i."'>".$i."</a> "; 
}; 
?>
<?php
echo "<a href='dataload2.php?page=$total_pages'>".'>|'."</a> "; // Goto last page
?>
