CodeIgniter:无法在Ubuntu 14.04上加载请求的文件:helpers/phpass_helper.php
我试图在我的基本控制器中加载Phpass帮助程序,以便散列我的密码。然而,它似乎没有加载到Ubuntu 14.04上。我尝试搜索,有人说可能是因为Linux区分大小写,所以我将文件从phpass_helper.php更改为phpass_helper.php。并使用以下代码将其加载:CodeIgniter:无法在Ubuntu 14.04上加载请求的文件:helpers/phpass_helper.php,php,codeigniter,ubuntu,phpass,Php,Codeigniter,Ubuntu,Phpass,我试图在我的基本控制器中加载Phpass帮助程序,以便散列我的密码。然而,它似乎没有加载到Ubuntu 14.04上。我尝试搜索,有人说可能是因为Linux区分大小写,所以我将文件从phpass_helper.php更改为phpass_helper.php。并使用以下代码将其加载: $this->load->helper('Phpass_helper'); 但它仍然给了我一个错误:无法加载请求的文件:helpers/phpass\u helper.php。有人知道它为什么不起作用吗
