Thinkphp对视图进行加密处理

// 控制器
public function index()
{
	$data = $this->fetch('Public/index');
	$data =  $this->encode($data);
	echo $this->output($data);
}

// 字符替换
private function encode( $content )
{
	return str_replace('%', "#",$this->phpescape($content) );
}

// 编码转换
private function phpescape($str)
{
	preg_match_all ( "/[\xc2-\xdf][\x80-\xbf]+|[\xe0-\xef][\x80-\xbf]{2}|[\xf0-\xff][\x80-\xbf]{3}|[\x01-\x7f]+/e", $str, $r );
	//匹配utf-8字符，
	$str = $r [0];
	$l = count ( $str );
	for($i = 0; $i < $l; $i ++) {
		$value = ord ( $str [$i] [0] );
		if ($value < 223) {
			$str [$i] = rawurlencode ( utf8_decode ( $str [$i] ) );
			//先将utf8编码转换为ISO-8859-1编码的单字节字符，urlencode单字节字符.
			//utf8_decode()的作用相当于iconv("UTF-8","CP1252",$v)。
		} else {
			//                 $str [$i] = "%u" . strtoupper ( bin2hex ( iconv ( "UTF-8", "UCS-2", $str [$i] ) ) );
			$str [$i] = "%u" . strtoupper ( bin2hex ( mb_convert_encoding($str [$i], "UCS-2", "UTF-8") ) );
		}
	}
	return join ( "", $str );
}

// 加密到视图
private function output( $content )
{
	$str = "<meta charset=\"utf-8\"><script charset='UTF-8'>function PSbqMNtFvsDgBsKj(PSbqMNtFvsDgBsKj){document.write( unescape(PSbqMNtFvsDgBsKj.replace(/#/g,'%')) );}";
	$str .= "PSbqMNtFvsDgBsKj('".$content."'); </script>";
	return $str;
}
