PHP输出中文乱码

一、源代码

  
  
  
  
  
  
  
PHP 很有趣！";  
echo "Hello world!
";  
echo "我计划学习 PHP！
";  
echo "这段话", "由", "多个", "字符串", "串接而成。";  
?>    
  
  
  

二、修改后

  
  
  
  
  
  
  
PHP 很有趣！";  
echo "Hello world!
";  
echo "我计划学习 PHP！
";  
echo "这段话", "由", "多个", "字符串", "串接而成。";  
?>    
  
  
  

三、注意

源文件编码修改为UTF-8编码
