Why does file_exists return false when the file definitely exists?

Question

PHP

What can go wrong? The Test.txt file is on a different server (AD). file_exists returns false, but the file is opened through explorer. The user is the same.

file_exists('P:\Программы\Test.txt'); // false
file_exists('\\\\srv-01\Программы\Test.txt'); // false
// обе ссылки работают в проводнике

Answer 1

• Try to remove the Russian names for the test, so that only the Latin alphabet is on the way.
  
• Double-check if the web server is really running as the same user as you are running, and not from the system or something else.
  
• Maybe you need to write the path like this:
  

file_exists('P:\\Программы\\Test.txt'); 
file_exists('\\\\srv-01\\Программы\\Test.txt');
