$a = $_GET['t'];
var_dump($a);
echo "then.......<hr>";
$b = htmlspecialchars($a);
var_dump($b);

http://localhost/test.php?t=中文字符

输出如下：

string(8)"中文字符"then.......

string(0)""

回复内容：

$a = $_GET['t'];
var_dump($a);
echo "then.......<hr>";
$b = htmlspecialchars($a);
var_dump($b);

http://localhost/test.php?t=中文字符

输出如下：

string(8)"中文字符"then.......

string(0)""

htmlspecialchars 的第三个参数是encoding

<code>$b = htmlspecialchars($a,ENT_QUOTES,'UTF-8');
</code>

这样应该就没问题了
