Du.t

Du.t is PHP routine that reveals encoding of the Utf8 characters. It is equivalent of "dump.t", but all functions necessary are defined inside and have no need to be included from the external files.

Code

<?php
 function unichr($dec) {
  if ($dec < 128) {
    $utf = chr($dec);
  } else if ($dec < 2048) {
    $utf = chr(192 + (($dec - ($dec % 64)) / 64));
    $utf .= chr(128 + ($dec % 64));
  } else {
    $utf = chr(224 + (($dec - ($dec % 4096)) / 4096));
    $utf .= chr(128 + ((($dec % 4096) - ($dec % 64)) / 64));
    $utf .= chr(128 + ($dec % 64));
  }
  return $utf;
} 
// include "unichr.t";


 function uniord($a) 
 {
   $M=strlen($a);
   $p=ord($a[0]);                    if($M==1) return $p;
   $p-=194;  $p*=64; $p+=ord($a[1]); if($M==2) return $p;
   $p-=2050; $p*=64; $p+=ord($a[2]);           return $p;

#   if($M==1) return ord($a[0]);
#   if($M==2) return 64*(ord($a[0])-194)+ord($a[1]);
#   if($M==3) return 64*( 64*(ord($a[0])-194)+ord($a[1]))-131200+ord($a[2]);
