Question

我有这段代码：

<?php
function paginate($reload, $page, $tpages) {
    $adjacents = 2;
    $prevlabel = "&lsaquo; Prev";
    $nextlabel = "Next &rsaquo;";
    $out = "";
    if ($page == 1) { 
        $out.= "<span style=\"display:none;\">" . $prevlabel . "</span>\n";
    } elseif ($page == 2) {
        $out.= "<li><a  href=\"" . $reload . "\">" . $prevlabel . "</a>\n</li>";
    } else {
        $out.= "<li><a  href=\"" . $reload . "&amp;page=" . ($page - 1) . "\">" . $prevlabel . "</a>\n</li>";
    }

    $pmin = ($page > $adjacents) ? ($page - $adjacents) : 1;
    $pmax = ($page < ($tpages - $adjacents)) ? ($page + $adjacents) : $tpages;
    for ($i = $pmin; $i <= $pmax; $i++) {
        if ($i == $page) {
            $out.= "<li><a href='' class=\"active\">" . $i . "</a></li>\n";
        } elseif ($i == 1) {
            $out.= "<li><a  href=\"" . $reload . "\">" . $i . "</a>\n</li>";
        } else {
            $out.= "<li><a  href=\"" . $reload . "&amp;page=" . $i . "\">" . $i . "</a>\n</li>";
        }
    }
    if ($page < $tpages) {
        $out.= "<li><a  href=\"" . $reload . "&amp;page=" . ($page + 1) . "\">" . $nextlabel . "</a>\n</li>";
    } else {
        $out.= "<span style='font-size:11px'>" . $nextlabel . "</span>\n";
    }
    $out.= "";
    return $out;
}
?>

如何在第一页出现5点。例如，当我在页面 1 时，我想要 1 2 3 4 5 ..但如果我将"$ adjacents=2;"更改为4.确实如此，当1页有一个1 2 3 4 5 ..但是当我移动到页面= 7，那么，页面显示1 2 3 4 5 6 7 8 9很多数字，或当我移动到页面= 12。显示的页面8 9 10 11 12 13 14 15 16 ..然而，我只想显示5位数。

如何仅在第一页和第二页时显示5位数页？当我翻页时，例如页面 12 就像这样。 10 11 12 13 14。

或在 1 页面中 1 2 3 4 5

或在页面 2 时，如此 2 3 4 5

或在页面 3 时，如此1 2 3 4 5 ..等等

您可以复制粘贴此脚本

<?php
function paginate($reload, $page, $tpages) {
    $adjacents = 2;
    $prevlabel = "&lsaquo; Prev";
    $nextlabel = "Next &rsaquo;";
    $out = "";
    if ($page == 1) { 
        $out.= "<span style=\"display:none;\">" . $prevlabel . "</span>\n";    $pmin = ($page > $adjacents) ? ($page - $adjacents) : 1;

    $adjacents = 4;


    $pmax = ($page < ($tpages - $adjacents)) ? ($page + $adjacents) : $tpages;
    for ($i = $pmin; $i <= $pmax; $i++) {
        if ($i == $page) {
            $out.= "<li><a href='' class=\"active\">" . $i . "</a></li>\n";
        } elseif ($i == 1) {
            $out.= "<li><a  href=\"" . $reload . "\">" . $i . "</a>\n</li>";
        } else {
            $out.= "<li><a  href=\"" . $reload . "&amp;page=" . $i . "\">" . $i . "</a>\n</li>";
