File_exists always false in laravel 4
提问by Vuk Stankovi?
I have written small CMS in Laravel 4 and I was working on it using wamp. Application was in wwwfolder and everything was working fine.
When I have finished with development, I moved an application to my live server and I have put application in rootfolder of my hosting (folder above public_html).
In some functions I'm checking if some files exist, and while I was on wamp, everything worked, but now file_exists()always returns false.
Folder permissions of the folder where files are stored are set to 755, and files are with same permissions.
我在 Laravel 4 中编写了小型 CMS，我正在使用 wamp 进行开发。应用程序在www文件夹中，一切正常。完成开发后，我将一个应用程序移动到我的实时服务器，并将应用程序放在root我的托管文件夹（上面的文件夹public_html）中。在某些函数中，我正在检查某些文件是否存在，当我在 wamp 时，一切正常，但现在file_exists()总是返回false. 存放文件的文件夹的文件夹权限设置为755，文件的权限相同。
I have already tried clearstatcache()and Safe mode cannot be an issue since it was removed in PHP 5.4. Any other ideas?
我已经尝试过clearstatcache()并且安全模式不会成为问题，因为它在 PHP 5.4 中被删除了。还有其他想法吗？
if(file_exists('public_html/repo/images/testimage.jpg')){
//do something
}
else{
echo "error";
}
I have checked several times, and file does exists if I try to access it via url
我已经检查了几次，如果我尝试通过 url 访问它，文件确实存在

Well, first you said you were in WAMP, it could be that folders were having uppercases. Remember, windows is not case-sensitive for folder while linux is.
好吧，首先你说你在 WAMP 中，可能是文件夹有大写。请记住，windows 对文件夹不区分大小写，而 linux 是。
Second, where's laravel's index.phpfile? (It's generaly in publicfolder), file_exists()is relative to it, so if your installation is: public_html/public/index.phpand repo/imagesis on publicfolder you should check for: file_exists('repo/images...');
二、laravel的index.php文件在哪里？（通常在public文件夹中），file_exists()是相对于它的，所以如果您的安装是：public_html/public/index.php并且repo/images在public文件夹中，您应该检查：file_exists('repo/images...');
Laravel is designed to keep its files outside of public access, so I suggest you put laravel's files and folders in the root /while moving everything in publicfolder to public_html. This way, you could check file existence relatively to public_htmlfolder.
Laravel 旨在将其文件保留在公共访问之外，因此我建议您将 Laravel 的文件和文件夹放在根目录中，/同时将文件夹中的所有内容移动public到public_html. 这样，您可以检查相对于public_html文件夹的文件存在。
file_exists('repo/images...');
file_exists('../app/views/hello.blade.php');
...
