This snippet works:

$handle=opendir($homedir); 
while ($file = readdir($handle)) {
        $retval[count($retval)] = $file; 
}                            
closedir($handle);           
sort($retval);                             
$cnt=count($retval);
echo "CNT: $cnt";
$int=0;
while($int<$cnt) {
        if(!is_dir($retval[$int])) {
                echo "File: $retval[$int]<br>";
        } else {  
                echo "Dir: $retval[$int]<br>";
        }
        $int++;
}

But if I change "if(!is_dir($retval[$int])) {" to "if(is_file($retval[$int])) {" it fails.

The way it fails is that all of the files fail to match as files, and are shown prefixed by "Dir:".

I could not reproduce the bug with a modified code, main difference is that I am using the full path in the is_file() function, as it should be. Code below works on PHP 4.0.3pl1 (RedHat 6.1 and Solaris 2.6):

$dir ="/path/to/phpdoc/en";
$handle=opendir($dir);
while ($file = readdir($handle)) {
    $retval[count($retval)] = $dir."/".$file; 
}                            
closedir($handle);           
sort($retval);                             
$cnt=count($retval);
echo "CNT: $cnt\n";
$int=0;
while($int<$cnt) {
  if(is_file($retval[$int])) {
          echo "File: ".$retval[$int]."\n";
  } else {  
          echo "Dir: ".$retval[$int]."\n";
  }
  $int++;
}

Please check the example Jesus gave. And report back whether it 
solves this or not.

I received an e-mail fromn whit@transpect.com to the effect that the code changes I made fixed the problem he had.

Closing this bug report now.
