一 : 引 言
在速度上,静态页面要比动态页面的比方php快很多,这是毫无疑问的,但是由于静态页面的灵活性较差,如果不借助数据库或其他的设备保存相关信息的话,整体的管理上比较繁琐,比方修改编辑.比方阅读权限限制等,但是,对应一些我们经常频频使用的文件,比方说,开发的新闻发布系统,我们不希望很多用户都读取数据库才显示结果,这样一方面消耗了服务器的资源,另一方面占去了浏览者大量可贵的响应时间,所有,有了"静态页面话"的做法,当前很多网站都采用这种技术,一般都是由管理后台控制,或者生成html直接显示,或者xhtml用css控制显示,或者生成xml用xslt显示,这些技术都不是难的,在这里我就浅显的说说生成html的方法.

二 : 预备知识
   
     模板技术:


[PHP]模板引擎Smarty深入浅出介绍--2005-12-31
[PHP]笑谈配置,使用Smarty技术 2006-01-04

     缓存技术:   

有些信息比方经常不变的,但是还是能变的信息放在缓存中以加快显示速度,这是很有价值的,所谓的缓存,通俗的理解就是一些保存在服务器端的共用信息.它是于服务器同生死的,我们在保存缓存的时候可以指定下次更新的时间的判断,比方要在5分钟更新一次,可以记录上次更新的时间,和当前时间比较,如果大于 5 分钟 ,读取数据库,更新换成,否则直接读取缓存数据,当然,缓存需要客户端用户激活的,只需一次.

ob_start()函数:打开输出缓冲区.
    函数格式 void ob_start(void)
    说明：当缓冲区激活时，所有来自PHP程序的非文件头信息均不会发送，而是保存在内部缓冲区。为了输出缓冲区的内容，可以使用ob_end_flush()或flush()输出缓冲区的内容。

Flush：刷新缓冲区的内容，输出。
    函数格式：flush()
    说明：这个函数经常使用,效率很高。

ob_get_contents ：返回内部缓冲区的内容。
    函数格式：string ob_get_contents(void)
    说明：这个函数会返回当前缓冲区中的内容，如果输出缓冲区没有激活,则返回 FALSE.

ob_get_length：返回内部缓冲区的长度。
    函数格式：int ob_get_length(void)
    说明：这个函数会返回当前缓冲区中的长度；和ob_get_contents一样，如果输出缓冲区没有激活,则返回 FALSE.

ob_end_clean：删除内部缓冲区的内容，并且关闭内部缓冲区
    函数格式：void ob_end_clean(void)
    说明：这个函数不会输出内部缓冲区的内容而是把它删除

ob_end_flush:发送内部缓冲区的内容到浏览器，并且关闭输出缓冲区
    函数格式：void ob_end_flush(void)
    说明：这个函数发送输出缓冲区的内容（如果有的话）

ob_implicit_flush：打开或关闭绝对刷新
    函数格式：void ob_implicit_flush ([int flag])
    说明：默认为关闭缓冲区，打开绝对输出后，每个脚本输出都直接发送到浏览器，不再需要调用 flush()     

     文件写入:   
int fwrite ( resource handle, string string [, int length] )
fwrite() 把 string 的内容写入 文件指针 handle 处。 如果指定了 length，当写入了 length 个字节或者写完了 string 以后，写入就会停止，视乎先碰到哪种情况。
fwrite() 返回写入的字符数，出现错误时则返回 FALSE 。

三 : 解决方案

思路: 开启 ob_start缓冲,当已经调出数据的时候获取 ob_get_contents,然后生成静态页,ob_end_clean清除缓冲.ok,就这么来,来看一个例子(php+mysql的结合):
创建数据库:

CREATE TABLE `bihtml` (
  `id` int(11) NOT NULL auto_increment,
  `szdtitle` varchar(16) NOT NULL,
  `szdcontent` text NOT NULL,
  PRIMARY KEY  (`id`)  
) TYPE=MyISAM;



获取当前的ID,并导入模板:

ob_start();
$id=_POST['id']
if(!isset($id)&&is_integer($id))
{
        @$db=new mysqli('localhost','root','admin','bihtml');
        $result=$db->fetch_one_array("select  * from szd_bi where id='$id'");
                        if(!empty($result))
                        {       
                        $tmp->assign(array(
                                "Szdtitle",htmlspecialchars($result['titles']),
                                "Szdcontent",$result['titles']));
                        }
        $tpl->display('default_1.tpl');
        $this_my_f= ob_get_contents();        //此处关键
        ob_end_clean();
        $filename = "$id.html";
        if(tohtmlfile_cjjer($filename,$this_my_f))
        echo "生成成功 $filename";
        else
        echo "生成识别";
        }
}

//把生成文件的过程写出函数
function tohtmlfile_cjjer($file_cjjer_name,$file_cjjer_content)
{
        if (is_file ($file_cjjer_name)){
                @unlink ($file_cjjer_name);
        }
$cjjer_handle = fopen ($file_cjjer_name,"w");
        if (!is_writable ($file_cjjer_name)){
                return false;
        }
        if (!fwrite ($cjjer_handle,$file_cjjer_content)){
                return false;
        }
fclose ($cjjer_handle); //关闭指针
return $file_cjjer_name;
}




四 : 说明事项

1: 一般建议管理员添加数据的时候就生成静态页面,可以考虑记录生成的文件名次和路径.

2:php主要是    ob_starts()和 ob_get_contents,生成静态页面的时候很有用,当然也可以考虑调出数据库直接替换模板里面的变量也是可以的.

3:主要的模板使用smarty,phplib都是可以的,smarty使用比较简易.

^\d+$　　//匹配非负整数（正整数 + 0）
^[0-9]*[1-9][0-9]*$　　//匹配正整数
^((-\d+)|(0+))$　　//匹配非正整数（负整数 + 0）
^-[0-9]*[1-9][0-9]*$　　//匹配负整数
^-?\d+$　　　　//匹配整数
^\d+(\.\d+)?$　　//匹配非负浮点数（正浮点数 + 0）
^(([0-9]+\.[0-9]*[1-9][0-9]*)|([0-9]*[1-9][0-9]*\.[0-9]+)|([0-9]*[1-9][0-9]*))$　　//匹配正浮点数
^((-\d+(\.\d+)?)|(0+(\.0+)?))$　　//匹配非正浮点数（负浮点数 + 0）
^(-(([0-9]+\.[0-9]*[1-9][0-9]*)|([0-9]*[1-9][0-9]*\.[0-9]+)|([0-9]*[1-9][0-9]*)))$　　//匹配负浮点数

^[A-Za-z0-9]+$　　//匹配由数字和26个英文字母组成的字符串
^\w+$　　//匹配由数字、26个英文字母或者下划线组成的字符串

利用正则表达式去除字串中重复的字符的算法程序：

var s="abacabefgeeii"
var s1=s.replace(/(.).*\1/g,"$1")
var re=new RegExp("["+s1+"]","g")
var s2=s.replace(re,"")
alert(s1+s2) //结果为：abcefgi
===============================
如果var s = "abacabefggeeii"
结果就不对了，结果为：abeicfgg
正则表达式的能力有限


1.确认有效电子邮件格式
下面的代码示例使用静态 Regex.IsMatch 方法验证一个字符串是否为有效电子邮件格式。如果字符串包含一个有效的电子邮件地址，则 IsValidEmail 方法返回 true，否则返回 false，但不采取其他任何操作。您可以使用 IsValidEmail，在应用程序将地址存储在数据库中或显示在 ASP.NET 页中之前，筛选出包含无效字符的电子邮件地址。

[Visual Basic]
Function IsValidEmail(strIn As String) As Boolean
' Return true if strIn is in valid e-mail format.
Return Regex.IsMatch(strIn, ("^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$")
End Function
[C#]
bool IsValidEmail(string strIn)
{
// Return true if strIn is in valid e-mail format.
return Regex.IsMatch(strIn, @"^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$");
}


2.清理输入字符串
下面的代码示例使用静态 Regex.Replace 方法从字符串中抽出无效字符。您可以使用这里定义的 CleanInput 方法，清除掉在接受用户输入的窗体的文本字段中输入的可能有害的字符。CleanInput 在清除掉除 @、-（连字符）和 .（句点）以外的所有非字母数字字符后返回一个字符串。

[Visual Basic]
Function CleanInput(strIn As String) As String
' Replace invalid characters with empty strings.
Return Regex.Replace(strIn, "[^\w\.@-]", "")
End Function
[C#]
String CleanInput(string strIn)
{
// Replace invalid characters with empty strings.
return Regex.Replace(strIn, @"[^\w\.@-]", "");
}


3.更改日期格式
以下代码示例使用 Regex.Replace 方法来用 dd-mm-yy 的日期形式代替 mm/dd/yy 的日期形式。

[Visual Basic]
Function MDYToDMY(input As String) As String
Return Regex.Replace(input, _
"\b(?<month>\d{1,2})/(?<day>\d{1,2})/(?<year>\d{2,4})\b", _
"${day}-${month}-${year}")
End Function
[C#]
String MDYToDMY(String input)
{
return Regex.Replace(input,
"\\b(?<month>\\d{1,2})/(?<day>\\d{1,2})/(?<year>\\d{2,4})\\b",
"${day}-${month}-${year}");
}
Regex 替换模式
本示例说明如何在 Regex.Replace 的替换模式中使用命名的反向引用。其中，替换表达式 ${day} 插入由 (?<day>...) 组捕获的子字符串。

有几种静态函数使您可以在使用正则表达式操作时无需创建显式正则表达式对象，而 Regex.Replace 函数正是其中之一。如果您不想保留编译的正则表达式，这将给您带来方便


4.提取 URL 信息
以下代码示例使用 Match.Result 来从 URL 提取协议和端口号。例如，“http://www.contoso.com:8080/letters/readme.html”将返回“http:8080”。

[Visual Basic]
Function Extension(url As String) As String
Dim r As New Regex("^(?<proto>\w+)://[^/]+?(?<port>:\d+)?/", _
RegexOptions.Compiled)
Return r.Match(url).Result("${proto}${port}")
End Function
[C#]
String Extension(String url)
{
Regex r = new Regex(@"^(?<proto>\w+)://[^/]+?(?<port>:\d+)?/",
RegexOptions.Compiled);
return r.Match(url).Result("${proto}${port}");
}
