Question

你好，我有这个代码：

  $thread_qry5= "SELECT * FROM xenProve_prove ORDER BY view_count DESC LIMIT 5";

                                    $row5 = XenForo_Application::get('db')->fetchAll($thread_qry5);

                                    foreach ( $row5 AS $rows5 ) {
                                        $viewid = $rows5['thread_id'];
                                        $viewtitle = $rows5['title'];
                                        $viewuser = $rows5['username'];

                                          $MostView .= 'div style="height:30px; width:640px; border-bottom:1px solid #999;padding:5px;">
                                                  <div style="height:40px; width:500px;float:left">
                                                      <div style="height:20px; width:650px; font-size:16px;color:#6d3f03;">'.$viewtitle.'</div>
                                                      <div style="height:20px; width:650px; font-size:12px;color:#6d3f03;">'.$viewuser.'</div>
                                                  </div>
                                          </div>';

如何替换此符号。=？ Xenforo系统不读取此符号（。=）我试过了：

 $MostView = 'div style="height:30px; width:640px; border-bottom:1px solid #999;padding:5px;">
                                                  <div style="height:40px; width:500px;float:left">
                                                      <div style="height:20px; width:650px; font-size:16px;color:#6d3f03;">'.$viewtitle.'</div>
                                                      <div style="height:20px; width:650px; font-size:12px;color:#6d3f03;">'.$viewuser.'</div>
                                                  </div>
                                          </div>' . $MostView;

但不起作用。我尝试了For循环anche while循环但不起作用。谢谢你

您正在尝试将字符串添加到另一个不存在的字符串（由concatenating assignment operator）。您必须先定义字符串：

$MostView = '';

然后：

foreach ( $row5 AS $rows5 ) {

    $viewid = $rows5['thread_id'];
    $viewtitle = $rows5['title'];
    $viewuser = $rows5['username'];

    $MostView .= 'div style="height:30px; width:640px; border-bottom:1px solid #999;padding:5px;">
                                              <div style="height:40px; width:500px;float:left">
                                                  <div style="height:20px; width:650px; font-size:16px;color:#6d3f03;">'.$viewtitle.'</div>
                                                  <div style="height:20px; width:650px; font-size:12px;color:#6d3f03;">'.$viewuser.'</div>
                                              </div>
                                      </div>';

我不认为这个问题与XenForo有关。如果您打开错误报告（只需检查Google或Stack Overflow），您将获得有关此错误的更多有用信息。

替换符号。= php
