PHP URL 中的分页不同符号

Question

当用户搜索 A B 时，URL 在第一页显示 A+B，但在第二页显示 A%20B，或者如果搜索 A&B 第一页有 A%26B，但第二页有 A&B。我该怎么做才能在接下来的每一页都保持相同的符号？

代码：

<?php
$total_pages = $query

$targetpage = "search.php";

$limit = 36; //Items per page
$page = $_GET['page'];
if($page) 
    $start = ($page - 1) * $limit;
else
    $start = 0;

    if ($page == 0) $page = 1;
    $prev = $page - 1;
    $next = $page + 1;
    $lastpage = ceil($total_pages/$limit);
    $lpm1 = $lastpage - 1;

    $pagination = "";
    if($lastpage > 1)
    {   
        $pagination .= "<div class=\"pagination\">";
        //previous button
        if ($page > 1) 
            $pagination.= "<a href=\"$targetpage?search=$search&submit=submit&page=$prev\">prev</a>";
        else
            $pagination.= "<span class=\"disabled\">prev</span>";   

        //pages 
        if ($lastpage < 7 + ($adjacents * 2)) //not enough pages to bother breaking it up
        {   
            for ($counter = 1; $counter <= $lastpage; $counter++)
            {
                if ($counter == $page)
                    $pagination.= "<span class=\"current\">$counter</span>";
                else
                    $pagination.= "<a href=\"$targetpage?search=$search&submit=submit&page=$counter\">$counter</a>";                    
            }
        }
        elseif($lastpage > 5 + ($adjacents * 2)) //enough pages to hide some
        {
            //close to beginning; only hide later pages
            if($page < 1 + ($adjacents * 2))        
            {
                for ($counter = 1; $counter < 4 + ($adjacents * 2); $counter++)
                {
                    if ($counter == $page)
                        $pagination.= "<span class=\"current\">$counter</span>";
                    else
                        $pagination.= "<a href=\"$targetpage?search=$search&submit=submit&page=$counter\">$counter</a>";                    
                }
                $pagination.= "...";

            //in middle; hide some front and some back
            elseif($lastpage - ($adjacents * 2) > $page && $page > ($adjacents * 2))

构建 URL 时，您必须手动对查询字符串进行编码。用PHP构造时用urlencode()，用JS构造URL时用encodeURIComponent()

PHP 示例

$pagination.= "<a href=\"$targetpage?search=".urlencode($search)."&submit=submit&page=1\">1</a>";

JS 示例

var pagination += "<a href=\"$targetpage?search="+encodeURIComponent(search)+"&submit=submit&page=1\">1</a>";
