Why would file_put_contents refuse to work for the following code?
$f = file_put_contents("files/r.js", "Some text here"); if ($f) print 1; else print 0;

The file_put_contents() writes data to a file. This function follows these rules when accessing a file: If FILE_USE_INCLUDE_PATH is set, check the include path for a copy of filename. Create the file if it does not exist.
PHP Create File - fopen() The fopen() function is also used to create a file. Maybe a little confusing, but in PHP, a file is created using the same function used to open files. If you use fopen() on a file that does not exist, it will create it, given that the file is opened for writing (w) or appending (a).
The file_exists() function checks whether a file or directory exists.
Is the directory /files chmoded to 777? sometimes php won't allow you to access directories if they don't have enough permission. I don't know about blank errors though.
Try to see if it has enough permissions, if not, then set it to 777 and try it.

Are you using the full path on the filesystem or are you trying to use the URI? I think this PHP function expects you to give the path as the file is found on the filesystem.
Relative paths should be okay though.
You may need to make sure the file exists and that it's permissions are set to 777. Sometimes I've found that it's not enough to just have the directory permissions set to 777 but the file must also already exist.
