Checking other server files

[TheFilmGod]

Can I use php to go into a directory on another server and check if a file name exists? I don't need to write on the other server, I only need to check if a file name exists.

 

Thanks!

You can... maybe.

 

If you have control over the other server, no problem.  I suspect you are wanting to validate a link instead?  That's harder.  Which one?

If you have access to write and push data through cURL to a 0777 directory and you want to avoid overwriting I'd suggest you simple say

$test = file_get_content($file_in_question)

if(strlen($test) < 100){

#No file found probably

}

That's right - I would like to validate a link. How do I do this?

if its being served, you can use file_get_contents()

Yes, but doesn't that require you to enable allow_url_fopen?  My understanding is that this opens a security hole and many hosts don't allow it.

I don't want to read or write on that "other" server. I only want to use php to see if a file in the file directory called "something.pdf" exists. Is this possible?
