执行php代码时我不断收到以下错误
解析错误:语法错误,第 37 行 /home/a9440109/public_html/gps_list.php 中的意外 T_CONSTANT_ENCAPSED_STRING
我试图定义字符编码,但仍然出现错误。请让我知道我做错了什么:
 <?php
 header('Content-type: text/html; charset=utf-8');
 //connect to the database
 include ('gps_db_connect.php');
 $query = "SELECT * from gps WHERE server_time > '20130130'";
 $result = mysqli_query($connection, $query) or die(' Error getting data');
 echo $query;
 $row_count = 0;

 $td_size=1;
 $td_font='Verdana'';
