How Can I Convert Files to UTF-8 During Website Migration?

Encoding Files in UTF-8 Format

This question addresses the challenge of converting files with non-UTF-8 encoding to UTF-8 format during website migration. The provided script retrieves file data but falls short in saving them in the desired UTF-8 encoding.

To resolve this issue, add the BOM (Byte Order Mark) for UTF-8. This unique character tells the system that the file is encoded in UTF-8. Insert the following line before saving the file:

file_put_contents($myFile, "\xEF\xBB\xBF".  $content); 

Here's the code with the addition:

header('Content-type: text/html; charset=utf-8');
mb_internal_encoding('UTF-8');
$fpath = "folder";
$d = dir($fpath);
while (False !== ($a = $d->read()))
{
    if ($a != '.' and $a != '..')
    {
        $npath = $fpath . '/' . $a;

        $data = file_get_contents($npath);
        
        file_put_contents('tempfolder/' . $a, "\xEF\xBB\xBF".$data);  // Append BOM for UTF-8
    }
}

This modification ensures that the $data is encoded in UTF-8, and the files will be saved in the correct format.
