What alternative text editors or programs can be used to identify and remove BOM in PHP files?

The Byte Order Mark (BOM) is a special character that can be added to the beginning of a PHP file, causing issues with the file's execution. To remove the BOM from PHP files, you can use alternative text editors such as Notepad++ or Sublime Text, which have options to save files without the BOM. Alternatively, you can use a PHP script to read the file contents, remove the BOM if present, and then save the file back without the BOM. 

$file = 'example.php';
$contents = file_get_contents($file);

if (substr($contents, 0, 3) == pack('CCC', 0xef, 0xbb, 0xbf)) {
    $contents = substr($contents, 3);
    file_put_contents($file, $contents);
    echo 'BOM removed successfully';
} else {
    echo 'No BOM found in the file';
}
