What are the permissions of this file? 

Also I'm not sure what it is exactly, you say directory but it seems that you look 
for a file.

How can I see the permissions of the file ?

I think this is not blocked.

Also use an absolute path with the drive name if the current drive is not the one 
where this file is (/foo is not an absolute path on windows, c:/foo is).

See the cacls command or the file property to read the perms.

Yes, it can be read, and if i test:

require_once("/class/test.php");

it is accepted, so i think who the problem is on the file_exists() function.

No idea what's wrong. Please provide all info I ask and tell us if part of the 
path is a junction or something similar. Is it actually a file? a directory?

Right, i'll send the archive, ok ?
<?
$includes = array();
$includes[0] = '/class/conexao.class.php';
$includes[1] = '/class/query.class.php';

for($i = 0; $i < count($includes);$i++){
   try{
	if(file_exists($includes[$i])){
		include_once($includes[$i]);
	}else{
		throw new Exception("Arquivo ".$includes[$i]." não existe.");
	}
	}catch(Exception $e){
			print "<script>alert('".$e->getMessage()."')</script>";
			exit;
		}
}
?>

No, thanks.

All I need is the info I asked here. The permission, are junctions part of the 
path, etc.

A simple test case like var_dump("/foo/bar.php"); is enough.

$test = var_dump("/class/autenticacao.class.php");
print $test;

returned: string(29) "/class/autenticacao.class.php"

have no junctions of the pach.

doh.... my mistake but...

ok, let me rephrase:

Please provide:

 - cacls output for this file
 - test using var_dump(file_exists($path));
 - test with an relative path (as in /foo/bar.php not c:/foo/bar.php) and tell 
us how it works
 - test with an absolute path (as in c:/foo/bar.php not /foo/bar.php) and tell 
us how it works

Which SAPI do you use? Apache? FastCgi? Can you try it using the command line 
too?

$test = var_dump(file_exists("/class/autenticacao.class.php"));
Returned: bool(false) 

$test = var_dump(file_exists("/class/autenticacao.class.php"));
Returned: bool(true)

I'm using Apache.

$test = var_dump(file_exists("/class/autenticacao.class.php"));
Returned: bool(false) 

$test = var_dump(file_exists("C:\Arquivos de programas\EasyPHP5.3.0\www\class\autenticacao.class.php"));
Returned: bool(true)

I'm using Apache.

//Sorry, i forget to update pach..

5.3.0? Please try using 5.3.6 or a snapshot.

Right, now I'll sleep, but if it dons't work, I back to post here after.

Since this didn't happen, the issue seams to have been resolved, hasn't it?
