解析错误：语法错误，php页面第3行出现意外的T_字符串

我现在正试图安静地纠正这个错误，但我不知道它出了什么问题。它抛出了解析错误

下面是HTML代码：mail.php

<form name="contactform" method="post" action="send_form_email.php">
 
<table width="450px">
 
<tr>
 
 <td valign="top">
 
  <label for="first_name">First Name *</label>
 
 </td>
 
 <td valign="top">
 
  <input type="text" name="first_name" maxlength="50" size="30">
 
 </td>
 
</tr>
 
<tr>
 
 <td valign="top"">
 
  <label for="last_name">Last Name *</label>
 
 </td>
 
 <td valign="top">
 
  <input type="text" name="last_name" maxlength="50" size="30">
 
 </td>
 
</tr>

 </td>
 
 <td valign="top">

我也有同样的问题

尝试在记事本++中打开它并更改文件的编码。
我在服务器上测试了代码，代码正常运行检查@ceadreak:before之前是否有一些奇怪的字符在本地主机上不起作用，对吗？仅在远程服务器上？
