ThinkPHP经常会遗忘的事

Submitted by gouki on 2010, January 28, 3:01 PM

使用THinkPHP框架开发程序，经常容易遗忘的事是什么呢？
1、app runtime没有及时更新
2、datamodel 缓存在更改表结构后没有刷新
3、数据缓存设定的时间太长。而在更改数据后没有主动刷新

4、模版缓存中的 include file 一般不会强制刷新。。

以上是开发注意事情，如果你发现改了一些设置或者其他什么后，死活不正常，请先检查以上四样。

PHP处理中文二三例

Submitted by gouki on 2009, March 13, 10:23 PM

在网上看到一个贴子，是说利用16进制输出所有中文，例子如下：

PHP代码
  1. <?php  
  2. $begin = hexdec ( " 4e00 " ); // 16进制转化为10进制  
  3. $end = hexdec ( " 9fa5 " );  
  4. $a = '["' ;  
  5. for ( $i = $begin ; $i <= $end ; $i ++ ) {  
  6.     $a .= ' \u ' . dechex ( $i );  
  7.     if ( $i % 10 == 0 ) {  
  8.         $a .= " <br> " ; 
  9.     } 
  10. } 
  11. $a .= ' "] ' ;  
  12. print_r (json_decode( $a ));  
  13. ?>  

看到这个例子，相信也能看得出了，那两个数字是不是与网上那种正则判断中文的很象啊。

由于json_encode转换中文时会把中文全部转换成16进制，这样在输出的时候就不会因为浏览器的字符集不支持而出现问题。所以同样的，利用decode也就相当于把这些16进制转换成中文了。其实并不需要这么复杂，只要在前面加上&#后面加上;就可以输出中文了。

看到这样的代码后想起昨天一个根据.net程序改的读取中文字的拼音的程序。

  102. }  
这是根据网上的例子改写而来，其实BUG不少，作业的作，是认不出的。还有GBK的字符也是认不出拼音的（好象GBK里的一些特殊字符的拼音规则和上面的数组并不一致）

不过，这些都算是我的备份吧。呵呵，同样，如果对拼音要求不高的朋友也可以拿来用用。

利用PHP裁剪图片

Submitted by gouki on 2008, December 6, 11:45 PM

其实，用PHP裁剪图片的原理是很简单的，无非就是用javascript画出一个方块，计算一下四个角的顶点，然后从原图中按照这四个点的坐标把当中的图切出来。

网上有现成的例子：http://www.coderhome.net/zifa/?p=351，不过里面的JS库用的是mootools的，如果要看，请直接到该网上去看，以后，等有空了，用jQuery的模拟一下，呵呵。
jQuery的插件还是很好开发的

强烈推荐google reader

Submitted by gouki on 2008, July 29, 10:22 PM

之所以会突然间提起这个也是有历史原因的，以前收藏别人的网站（指RSS），都是用的greatnews，而且也用了有两年之久，之后也使用过很多客户端软件，什么周伯通啦之类的，包括一些特定的客户端也用了不少，象foxmail,maxthon等，但最后还是坚持 使用了GreatNews。

可是，为什么我现在又推荐google reader了呢？这当然也有原因的，最初greatnews的时候并没有想过我会有两台电脑。也没有想过会有三台，四台这样的情况，因此一个greatnews我就完全足够了。然而却往往事与愿违，在单位的时候、在家的时候、出门在外的时候都有可能会关注这些收藏的网址，怎么办？客户端软件的局限性就出来了。

如果我每台机器都装一个，那么势必我每条新闻都要确认多次我是否读过，这样的人生活着还有什么意义？于是想到了在线阅读。。。在线阅读，当然要首选网络最快的了，哪个网站网络最快？毫无疑问，google打倒了几乎所有的对手。需要其他选择吗？需要理由吗？那就再加一个理由，几乎所有的feed都支持google，其他一些在线阅读软件他敢这么保证吗？

而且，使用google reader我也不需要再重新注册了，因为我本来就有gmail。功能也不比网上那些在线阅读网站差，再配合上firefox的google reader监视插件，相当于我装了一个C/s客户端。这些都不是主要的，主要的是，我在一个地方mark feed is read之后，使用其他电脑的时候，我可以直接跳过这些，如果实在重要的，我还可以加星、加到我的共享，同时将我的共享网址发给别人的时候，他们也可以和我一样分享我认为有意义的东西，岂不美哉？

故此，推荐google reader，认为枪文也好，放屁也罢，这是我的选择，你可以不赞同也可以反对，但我不会改变，除非你有更好的理由来说服我。Over，黑黑
