Question

我已经在php中为我的网站实施了分页系统，唯一的问题是如下：
假设我的网址分页为www.abc.com/search.php?mode=study&query=a，目前每页显示20个结果，当我使用分页浏览结果时，网址会更改为www.abc.com/search.php?mode=study&query=a&page=2，www.abc.com/search.php?mode=study&query=a&page=2&page=3和{{ 1}}，所以我面临的问题是当我浏览结果时，每次页面变量都附加到网址时，这真的很烦人。
我的分页代码是。

www.abc.com/search.php?mode=study&query=a&page=2&page=3&page=4

我知道问题在于<?php function displayPaginationBelow($per_page,$page,$total){ $page_url="http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]&"; $adjacents = "2"; $page = ($page == 0 ? 1 : $page); $start = ($page - 1) * $per_page; $prev = $page - 1; $next = $page + 1; $setLastpage = ceil($total/$per_page); $lpm1 = $setLastpage - 1; $setPaginate = ""; if($setLastpage > 1) { $setPaginate .= "<ul class='setPaginate'>"; $setPaginate .= "<li class='setPage'>Page $page of $setLastpage</li>"; if ($setLastpage < 7 + ($adjacents * 2)) { for ($counter = 1; $counter <= $setLastpage; $counter++) { if ($counter == $page) $setPaginate.= "<li><a class='current_page'>$counter</a></li>"; elseif (isset($_GET['page'])) { unset($_GET['page']); $page_url = http_build_query($_GET); echo $page_url; $setPaginate.= "<li><a href='{$page_url}page=$counter'>$counter</a></li>"; } else $setPaginate.= "<li><a href='{$page_url}page=$counter'>$counter</a></li>"; } } elseif($setLastpage > 5 + ($adjacents * 2)) { if($page < 1 + ($adjacents * 2)) { for ($counter = 1; $counter < 4 + ($adjacents * 2); $counter++) { if ($counter == $page) $setPaginate.= "<li><a class='current_page'>$counter</a></li>"; else $setPaginate.= "<li><a href='{$page_url}page=$counter'>$counter</a></li>"; } $setPaginate.= "<li class='dot'>...</li>"; $setPaginate.= "<li><a href='{$page_url}page=$lpm1'>$lpm1</a></li>"; $setPaginate.= "<li><a href='{$page_url}page=$setLastpage'>$setLastpage</a></li>"; } elseif($setLastpage - ($adjacents * 2) > $page && $page > ($adjacents * 2)) { $setPaginate.= "<li><a href='{$page_url}page=1'>1</a></li>"; $setPaginate.= "<li><a href='{$page_url}page=2'>2</a></li>"; $setPaginate.= "<li class='dot'>...</li>"; for ($counter = $page - $adjacents; $counter <= $page + $adjacents; $counter++) { if ($counter == $page) $setPaginate.= "<li><a class='current_page'>$counter</a></li>"; else $setPaginate.= "<li><a href='{$page_url}page=$counter'>$counter</a></li>"; } $setPaginate.= "<li class='dot'>..</li>"; $setPaginate.= "<li><a href='{$page_url}page=$lpm1'>$lpm1</a></li>"; $setPaginate.= "<li><a href='{$page_url}page=$setLastpage'>$setLastpage</a></li>"; } else { $setPaginate.= "<li><a href='{$page_url}page=1'>1</a></li>"; $setPaginate.= "<li><a href='{$page_url}page=2'>2</a></li>"; $setPaginate.= "<li class='dot'>..</li>"; for ($counter = $setLastpage - (2 + ($adjacents * 2)); $counter <= $setLastpage; $counter++) { if ($counter == $page) $setPaginate.= "<li><a class='current_page'>$counter</a></li>"; else $setPaginate.= "<li><a href='{$page_url}page=$counter'>$counter</a></li>"; } } } if ($page < $counter - 1){ $setPaginate.= "<li><a href='{$page_url}page=$next'>Next</a></li>"; $setPaginate.= "<li><a href='{$page_url}page=$setLastpage'>Last</a></li>"; }else{ $setPaginate.= "<li><a class='current_page'>Next</a></li>"; $setPaginate.= "<li><a class='current_page'>Last</a></li>"; } $setPaginate.= "</ul>\n"; } return $setPaginate; }变量，需要帮助解决这个小问题

Answer 1

$page_url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; //Create the url
$page_url = preg_replace("/(page\=[0-9]+[\&]*)/", "", $page_url); // Delete page query string.
if($page_url[strlen($page_url) - 1 ] !== "&"){ // If last char is not &
    $page_url .= "&"; // add &
}

Answer 2

在添加新页面参数之前，您需要删除旧页面参数。因此，请通过unset()

删除参数
