Question

我正在试图找出如何删除逗号，比如说 [＆＃39; address_2＆＃39;]字段，如果这是空的，如果没有输入，也不会显示[＆＃39; tel＆＃39;]电话号码的图标，这似乎很难在回声中工作。

          $numrows = mysql_num_rows($query);
                if ($numrows > 0){

                    while ($row = mysql_fetch_assoc($query)) {
                        echo "<div class='result-container'>

                                  <div class='result-wrap'>

                                        <div class='leftbox'> 

                                            <div class='titlebox'>
