QUESTION
I've reviewed a number of ways to determine that a directory is empty or not, and many indicate that $isDirEmpty = !(new \FilesystemIterator($dir))->valid();
is a good choice, except that the directory path in the $dir parameter must exist or else an UnexpectedValueException
is thrown. Please see How can I use PHP to check if a directory is empty? for more details about using this method.
However, this and other examples first need to use other functions/statements to determine if the directory exists before using FileSystemIterator to retrieve the iterator and test its item, but these often cache information about the directory and that needs to be explicitly released after they are used, which many of these examples do not do.
To get around these extra 'details' and aid in my debugging, I've decided to implement the FileSystemIterator technique in a function that uses a try/catch block and instead of the valid method
that returns true if the file system item is valid (whatever that means) or false, I'm using the getPathname
method so I can see the actual directory/file's path name when I debug the code.
Here is my function, but I need the catch() parameter to finish it:

, you can catch it specifying its type in the catch statement like this:
QUESTION
I am trying to achieve automatic subdomain creation. I have read a lot of tutorials including:
I understood the concept and I implemented it with success in the past for user profiles, but this is a different case and I am stuck.
What I want to do, is basically something like pen.io as functionality. A user creates a page with a password and then, that page name converts into a subdomain.
I thought of doing a function that runs on the index page of the main website and that one used afterwards in HTACCESS to have something like index.php?subdomain=test and that one to redirect to test.domain.tld
EDIT:
Here is the current implementation that works when clicking on a link, but it doesn't work when accessing the url directly from the browser:
Code used in view.php:

Correct your rewrite rules
Something like [aA-zZ]
should be [a-zA-Z]
and the RewriteRule
should be only after the RewriteCond
and not in front of it and two of them. And do you really want to force a -
inside the subdomain with ([a-z0-9][-a-z0-9]+)
? Maybe you should check this answer. Note: The www
inside of your domain is a subdomain as well. So it would rewrite to sub.php?url=www
With the corrected rewriting random.domain.tld
returns the content of random.domain.tld/sub.php?url=random
. But at the moment your sub.php does not return content. Instead it returns a http redirect to the URL random.domain.tld
. This means your sub.php produces an infinite loop on itself. Instead sub.php should only contain something like .
Maybe you did not understand how URL rewriting works. Then read this answer for further explanation.

QUESTION
I'm working with text/HTML diffing engine that's using XML in it's core but we're inputting HTML5 data, I wonder how to take care of tags that don't need to be closed in HTML5, but must be closed in XML. For Example:
Do I need to convert every tag manually (Just like this example)?
Is there a tool that would do this for me? And save a headache escaping all self-closing HTML tags?
For example xml_parse()
runs following code like it has an error, but body
has a valid HTML which is invalid XML:

I've a website that has a profile page. Obviously all users have an own profile page available on this url: domain.dev/profile?user=%username%.
Now, I want to do that every user can see the profile on username.domain.dev.
I saw many post about that like How to let PHP to create subdomain automatically for each user? but it doesn't resolve my problem.
I've my website on ubuntu (nginx) and also on Windows IIS 10. How can I do that? Do you have some other link/question that can I see? Or some suggestion?
