php版本是5.4.3，选用源代码安装，保存完配置文件，就空白了。把index.php里边的error_reporting(0)注释掉后，显示出了一组错误如下：

Strict Standards: Declaration of companyModel::delete() should be compatible with model::delete($table, $id) in E:\zentaopms\module\company\model.php on line 125

Strict Standards: Non-static mothod sql:select() should not be called statically, assuming $this from incompatible context in  E:\zentaopms\lib\dao\dao.class on line 705

Strict Standards: Non-static mothod sql:factory() should not be called statically, assuming $this from incompatible context in  E:\zentaopms\lib\dao\dao.class on line 1139

下面还有几个错误，与上面几个基本相同。请问这是什么原因呢？
