php5.3不支持ereg函数
在drupal本地安装时出现了如下错误
Deprecated: Function ereg() is deprecated in E:\myDocs\2010\03\drupal\includes\file.inc on line 911
安装环境是wanp集成了php5.3版权，在druapl的官方网站申请：其不支持php5.3：
Note that some contributed modules may not be compatible with PHP 5.3
http://drupal.org/requirements
而php的官方手册则作如下申明：
This function has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 6.0.0. Relying on this feature is highly discouraged.
