Find file on the server

Sorry for not putting this as a comment, but I still have no reputation for such ...

I had a similar problem in the company where I worked, where PHP created the file on the server but did not create it with the read permissions due, the solution I found was to change the permission of the file soon after its generation, with the command chmod , solved my problem.

See an example:

<?php
// Escrita e leitura para o proprietario, nada ninguem mais
chmod ("/somedir/somefile", 0600);

// Escrita e leitura para o proprietario, leitura para todos os outros
chmod ("/somedir/somefile", 0644);

// Tudo para o proprietario, leitura e execucao para os outros
chmod ("/somedir/somefile", 0755);

// Tudo para o proprietario, leitura e execucao para o grupo do prop
chmod ("/somedir/somefile", 0750);
?>

The function chmod returns true or false, and in your case you could do something like:

<?php
if(chmod("ATUALIZA.TXT", 0644)){
  //instruções para lidar com o ficheiro
  ...
}
?>

Another thing is, why use .txt if there are options like JSON and XML ?

Since the shell_exec() function is very dangerous to the system, here is another function that can solve your problem.

By PHP documentation , you can use the command copy() , which will copy a source to a destination.

copy ( 'R:\ATUALIZA.TXT' , 'c:\pata_do_wamp\seu_site\ATUALIZA.TXT' );
