使用 CodeIgniter 删除文件？
我不确定这是否是使用 CodeIgniter 删除单个文件（例如图像）的正确函数。
$this->load->helper('file');
delete_files('path')
http://codeigniter.com/user_guide/helpers/file_helper.html
但是它列出了该函数用于删除整个目录，并且没有提及它如何处理单个文件（如果仅给出 1 个文件的路径）。在开始测试之前，我想我应该检查一下是否有人遇到过这个问题？
我只是想使用 CodeIgniter 函数来删除单独上传的图像（例如用户个人资料图像），但我无法在文档/用户指南中找到任何可以帮助我实现此目的的内容（是的，我知道我首先需要拥有适当的权限那个，但这超出了这个问题的范围）。
关于 unlink()
我所希望的是一个内置的 CI 函数，它会提醒我一些愚蠢的事情，例如“无删除权限”或其他因素，例如“文件正在使用”。我发现 unlink() 有时不起作用（不会抛出错误）。所以我才问...
I'm not sure if this is the proper function to delete a single file (say an image) using CodeIgniter.
$this->load->helper('file');
delete_files('path')
http://codeigniter.com/user_guide/helpers/file_helper.html
However it lists that this function is to delete entire directories, and makes no mention of how it handles individual files (if a path to only 1 file is given). Before I start testing with it, I figured I would check if anyone has ran into this problem before?
I simply want to use a CodeIgniter function to delete individually uploaded images (say user profile images) but I am unable to find anything in the documentation / user guide that helps me achieve this (yes I know I need to have proper permissions first and all that, but that is out of scope of this question).
regarding unlink()
what I was hoping for is a built in CI function that would alert me to something stupid like "no delete permission" or other factors like "file is in use". I found unlink() to sometimes not work (without throwing me an error). Hence why I asked...

正如我在评论中发布的，您可以利用 PHP 的
unlink()函数。但是，这似乎在返回 false 时返回E_WARNING错误。就像我在评论中所说的那样，您可以利用错误抑制，但如果无法删除文件，仍然以适当的方式处理错误。As I posted in the comments, you could utilize PHP's
unlink()function. However, this seems to return anE_WARNINGerror upon returning false. Like I also stated in the comments, you could utilize error suppression, but still handle the error in an appropriate manner, should it fail to delete a file.
