警告：filectime（）：stat失败的路径

Question

I am trying to get the date in which a file was modified or created with PHP. To do this I am using filectime function but it is giving me always the following error:

Warning: filectime(): stat failed for path

where path is the route in which I have stored the file.

The route is something similar to this:

http://MYIP/documents/animals document 1.pdf
http://MYIP/documents/animals document 2.pdf
...

and I have to replace the url to codify the spaces of the file:

$path= str_replace(' ', '%20', $path);

If I do this I can use a link to open this file on my browser but it shows the warning that I have put before if I try to use the same path on filectime function.

Am I missing something?

Thanks in advance!

The filectime function expects a string path as a parameter. It is just a wrapper function over the usage of Posix stat system call.

The system call:

int stat(const char *pathname, struct stat *buf);

So, it expects a parameter as though it's on your filesystem. The URL gets encoded to have a neat white-space-less identifier on the server side to execute appropriate scripts.

Don't bother with that "codification"! Just use a standard string path as you'd use on your UNIX shell, relative to the script directory.

In this case, just provide the right path to the PHP function!

filectime("documents/animals document 2.pdf");
