        }
        else
        {
            $page = (int)$_GET['page'];
        }
        $start_f = ($page-1) * $per_page;
$query = mysqli_query($conn, " SELECT * FROM `posts` p INNER JOIN `users` u 
WHERE p.p_author = u.u_id AND `p_category` = '$_GET[category]' ORDER BY `p_id` DESC LIMIT $start_f , $per_page" );
while ( $post = mysqli_fetch_assoc($query)) {
# code...
?>

    <div class="col-xs-12 col-sm-6 col-md-3" style="margin-top: 20px;">
        <div class="col-item" >
            <div class="post-img-content">

                <img src="<?php echo $post['p_image']; ?>" style="width: 100%; height: 100%;" class="img-responsive" />

链接连接错误，use & instead of ? again：

<?php
}
                           $page_sql = mysqli_query($conn, "SELECT * FROM 
 `posts` WHERE `p_category` = '$_GET[category]'");
                           $count_page = mysqli_num_rows($page_sql);
                           $total_page = ceil($count_page/$per_page); /// cail for make value int

                            ?>  
                            <nav class="text-center">
                            <ul class="pagination">
                            <?php 
                           for($i = 1 ; $i <= $total_page; $i++)
                           {
                            echo '<li '.($page==$i ? 'class="active"' : '').' ><a href="category.php?category='.$_GET['category'].'&page='.$i.'">'.$i.'</a></li>';
                           }

                           ?>

PHP分页不起作用
