หวังว่ามันจะช่วยได้ ขอให้มีความสุขในการเขียนโค้ด!

บางอย่างเช่นนี้ควรจะได้ผล

$pages_content = '';

$minPage = max(1, $page - 2);
$maxPage = min($pages, $page + 2);
for($i = $minPage; $i <= $maxPage;$i++) {
    if($pages >= 1) {
        if($i == $page) {
            $pages_content .= "<b>{$i}</b>";
        }
        else {
            $pages_content .= "<a href='/th?page={$i}'>{$i}</a>";
        }
    }
}

หากจำนวนหน้าสามารถมีได้มาก ให้ลองใช้การแบ่งหน้าแบบ "ลอการิทึม":

(โค้ด PHP ตัวอย่างรวมอยู่ในคำตอบของฉันที่นั่น)

การแบ่งหน้าพื้นฐานใน PHP โดย Amol Gholap

public function getPagination($pid,$totalCount=500,$countPerPage=50,$pageNumberingStart=1,$url=BASE_PATH,$maxDisplayPageNumbers=10){
        $response= "<a href='/th".($pid > 1 ? "$url?pid=".($pid-1) : "" )."' style='text-decoration:none'><-</a>";
        $maxNum = $pid+($maxDisplayPageNumbers/2);
        $minNum = $pid-($maxDisplayPageNumbers/2)+1;//-$pid);
        $response.= $minNum > 1 ? "<a style='text-decoration:none'>---</a>":"";
        for($t=0;$t<$totalCount;$t+=$countPerPage){
            if(($maxNum >= $pageNumberingStart && $minNum <= $pageNumberingStart)
                ){
                if($pid == $pageNumberingStart)
                    $response.= " <a href='/th$url?pid=$pageNumberingStart'><strong>".$pageNumberingStart."</strong></a> ";
                else
                    $response.= " <a href='/th$url?pid=$pageNumberingStart' style='text-decoration:none'>".$pageNumberingStart."</a> ";
            }
            $pageNumberingStart++;
        }
        $response.= $maxNum < $pageNumberingStart-1 ? "<a style='text-decoration:none'>---</a>":"";
        $response.= "<a href='/th".($pid < $pageNumberingStart ? "" : "$url?pid=".($pid+1) )."' style='text-decoration:none'>-></a>";
        return $response;
    }

รับหมายเลขหน้าปัจจุบัน

if (isset($_GET['pageno'])) {
    $pageno = $_GET['pageno'];
} else {
    $pageno = 1;
}

สูตรการแบ่งหน้า

$no_of_records_per_page = 10;
$offset = ($pageno-1) * $no_of_records_per_page;

รับจำนวนหน้าทั้งหมด

$total_pages_sql = "SELECT COUNT(*) FROM table";
$result = mysqli_query($conn,$total_pages_sql);
$total_rows = mysqli_fetch_array($result)[0];
$total_pages = ceil($total_rows / $no_of_records_per_page);

การสร้าง SQL Query สำหรับการแบ่งหน้า

$sql = "SELECT * FROM table LIMIT $offset, $no_of_records_per_page";
