精简版uc_client
在应用需要整合ucenter时候需要用到 uc_client 目录，而往往我们并不需要那么多功能，那么有没有简单的方法呢？下面一个文件搞定ucenter 主要接口，包含，注册，登录，退出，同步登录相关接口。
德语字符排序
mb_internal_encoding("UTF-8");
$array1 = array('aümg', 'abc', 'aécas', 'bdö', 'äsasf', 'aäfa');
uasort($array1, 'utf_8_german::cmp');
var_dump($array3);
Result: array(6) { [5]=> string(5) "aäfa" [1]=> string(3) "abc" [2]=> string(6) "aécas" [0]=> string(5) "aümg" [4]=> string(6) "äsasf" [3]=> string(4) "bdö" }
__destruct函数引起return失效
当在一个function中new一个包含__destruct的对象时，如果__destruct中exit; 将导致function return value失效.
function __destruct() {
$this->isFinalized = true;
$cd = null;
$this->cdRec = null;
//exit;
}
PHPExcel解决内存占用过大问题-设置单元格对象缓存
PHPExcel是一个很强大的处理Excel的PHP开源类，但是很大的一个问题就是它占用内存太大，从1.7.3开始，它支持设置cell的缓存方式，但是推荐使用目前稳定的版本1.7.6，因为之前的版本都会不同程度的存在bug，以下是其官方文档：
PHPExcel1.7.6官方文档 写道
PHPExcel uses an average of about 1k/cell in your worksheets, so large workbooks can quickly use up available memory. Cell caching provides a mechanism that allows PHPExcel to maintain the cell objects in a smaller size of memory, on disk, or in APC, memcache or Wincache, rather than in PHP memory. This allows you to reduce the memory usage for large workbooks, although at a cost of speed to access cell data.
PHPExcel平均下来使用1k/单元格的内存，因此大的文档会导致内存消耗的也很快。单元格缓存机制能够允许PHPExcel将内存中的小的单元格对象缓存在磁盘或者APC，memcache或者Wincache中，尽管会在读取数据上消耗一些时间，但是能够帮助你降低内存的消耗。
PHPExcel1.76.官方文档 写道
By default, PHPExcel still holds all cell objects in memory, but you can specify alternatives. To enable cell caching, you must call the PHPExcel_Settings::setCacheStorageMethod() method, passing in the caching method that you wish to use.
默认情况下，PHPExcel依然将单元格对象保存在内存中，但是你可以自定义。你可以使用PHPExcel_Settings::setCacheStorageMethod()方法，将缓存方式作为参数传递给这个方法来设置缓存的方式。
