note 102274 added to function.rename

rename() is working on Linux/UNIX but not working on Windows on a directory containing a file formerly opened within the same script. The problem persists even after properly closing the file and flushing the buffer.

<?php
$fp = fopen ("./dir/ex.txt" , "r+");
$text = fread($fp, filesize("../dir/ex.txt"));
ftruncate($fp, 0);
$text2 = "some value";
fwrite ($fp,  $text2 );
fflush($fp);
fclose ($fp);
if (is_resource($fp))
	fclose($fp);
rename ("./dir", ".dir2"); // will give a «permission denied» error
?>

Strangely it seem that the rename command is  executed BEFORE the handle closing on Windows.

Inserting a sleep() command before the renaming cures the problem.

<?php
$fp = fopen ("./dir/ex.txt" , "r+");
$text = fread($fp, filesize("../dir/ex.txt"));
ftruncate($fp, 0);
$text2 = "some value";
fwrite ($fp,  $text2 );
fflush($fp);
fclose ($fp);
if (is_resource($fp))
	fclose($fp);
sleep(1);	// this does the trick
rename ("./dir", ".dir2"); //no error 
?>
