Working with rename function in PHP

Question

There is a file within the directory and I am trying to use rename( arg1, arg2 ) to rename the arg1 file.

However, the arg1 file contains Asian letters and I get the message that the file is not available.

how can I solve this issue

thanks

    $elements = scandir($dir);


foreach ($elements as $key => $value) 
{

    rename("./$value", "$newname");

}

Be sure to put the paths correctly:

$elements = scandir($dir);
foreach ($elements as $key => $value) {
    rename($dir.'/'.$value, $dir.'/'.$newname);
}

To be less abstract, assume $dir is something like "/home/someuser/somefiles" and your script is located at "/var/www/script.php", you are getting all files (eg "oldname.txt") from scandir($dir), so the absolute path to the file is "/home/someuser/somefiles/oldname.txt", but you are passing "./oldname.txt" to the rename function, which is in fact "/var/www/oldname.txt"
