fwrite UTF-8 without BOM

To write data to file encoded in UTF-8 (with BOM):

function writeStringToFile($file, $string){
  $f=fopen($file, "wb");
  $string="\xEF\xBB\xBF".$string; // UTF-8
  fputs($f, $string);
  fclose($f);
}

How do I write data encoded in UTF-8 without BOM?

Edit

A screenshot from notepad++ with encodings:

The string "\xEF\xBB\xBF" match the «UTF-8 with BOM» format.

If you have a string with this format and want to write it in a file with a «simple» UTF-8, you have to remove theses characters. This can be done in various way, for example with preg_replace : 

function writeStringToFileUTF8($file, $string){
  $string = preg_replace("`\xEF\xBB\xBF`", "", $string);
  // this is equivalent as fopen(w)/fputs()/fclose()
  file_put_contents($file, $string);
}

The only way I found is removing the BOM after creating the file.

<?php // change the pathname to your target file which you want to remove the BOM $pathname = "./test.txt"; $file_handler = fopen($pathname, "r"); $contents = fread($file_handler, filesize($pathname)); fclose($file_handler); for ($i = 0; $i < 3; $i++){ $bytes[$i] = ord(substr($contents, $i, 1)); } if ($bytes[0] == 0xef && $bytes[1] == 0xbb && $bytes[2] == 0xbf){ $file_handler = fopen($pathname, "w"); fwrite($file_handler, substr($contents, 3)); fclose($file_handler); printf("%s BOM removed. \n", $pathname); } ?>

function writeStringToFile($file, $string){
    $f=fopen($file, "wb");
    // $file="\xEF\xBB\xBF".$file; // UTF-8 <-- this is UTF8 BOM
    fputs($f, $string);
    fclose($f);
}
