Really? Then what is the value of $trans_tbl['ASCII'][13]? 
That looks zero-length to me.  
 
php_str_replace_in_subject() previously moved the search 
array forward and didn't move the replace array. This has 
since been fixed in CVS.

But as you can see the search and the replace array in the function
have no 0 length values and all three arrays are of the same size.

In php_str_replace_in_subject(), if a value in the search 
array is of 0 length, the search array internal pointer is 
moved ahead, but not the replace array. Shouldn't they 
both be moved ahead? This would produce the results 
panacode is expecting, but it would break BC, but I don't 
see any documentation that covers this behaviour. Unless 
I'm blind, of course, which I may be.

Sorry but there is a bug in the str_replace function. Reproduced under
4.2.2 and 4.3.2

function recode_charset($string,$cs_from,$cs_to) {
  $trans_tbl["ASCII"] = array("&", "�", "�", "�", "�", "�", "�", "�",
"�", "�", "�", "�", "�", "", "�", "�", "�", "�", "�", "�", "�", "�",
"�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�",
"�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�",
"�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�",
"�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�",
"�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�", "�",
"�", "�", "�", "�");

  $trans_tbl["UNICODE"] = array("&#x26;", "&#161;", "&#162;", "&#163;",
"&#164;", "&#165;", "&#166;", "&#167;", "&#168;", "&#169;", "&#170;",
"&#171;", "&#172;", "&#173;", "&#174;", "&#175;", "&#176;", "&#177;",
"&#178;", "&#179;", "&#180;", "&#181;", "&#182;", "&#183;", "&#184;",
"&#185;", "&#186;", "&#187;", "&#188;", "&#189;", "&#190;", "&#191;",
"&#192;", "&#193;", "&#194;", "&#195;", "&#196;", "&#197;", "&#198;",
"&#199;", "&#200;", "&#201;", "&#202;", "&#203;", "&#204;", "&#205;",
"&#206;", "&#207;", "&#208;", "&#209;", "&#210;", "&#211;", "&#212;",
"&#213;", "&#214;", "&#215;", "&#216;", "&#217;", "&#218;", "&#219;",
"&#220;", "&#221;", "&#222;", "&#223;", "&#224;", "&#225;", "&#226;",
"&#227;", "&#228;", "&#229;", "&#230;", "&#231;", "&#232;", "&#233;",
"&#234;", "&#235;", "&#236;", "&#237;", "&#238;", "&#239;", "&#240;",
"&#241;", "&#242;", "&#243;", "&#244;", "&#245;", "&#246;", "&#247;",
"&#248;", "&#249;", "&#250;", "&#251;", "&#252;", "&#253;", "&#254;",
"&#255;");

  $trans_tbl["HTML"] = array("&amp;", "&iexcl;", "&cent;", "&pound;",
"&curren;", "&yen;", "&brvbar;", "&sect;", "&uml;", "&copy;", "&ordf;",
"&laquo;", "&not;", "&shy;", "&reg;", "&macr;", "&deg;", "&plusmn;",
"&sup2;", "&sup3;", "&acute;", "&micro;", "&para;", "&middot;",
"&cedil;", "&sup1;", "&ordm;", "&raquo;", "&frac14;", "&frac12;",
"&frac34;", "&iquest;", "&Agrave;", "&Aacute;", "&Acirc;", "&Atilde;",
"&Auml;", "&Aring;", "&AElig;", "&Ccedil;", "&Egrave;", "&Eacute;",
"&Ecirc;", "&Euml;", "&Igrave;", "&Iacute;", "&Icirc;", "&Iuml;",
"&ETH;", "&Ntilde;", "&Ograve;", "&Oacute;", "&Ocirc;", "&Otilde;",
"&Ouml;", "&times;", "&Oslash;", "&Ugrave;", "&Uacute;", "&Ucirc;",
"&Uuml;", "&Yacute;", "&THORN;", "&szlig;", "&agrave;", "&aacute;",
"&acirc;", "&atilde;", "&auml;", "&aring;", "&aelig;", "&ccedil;",
"&egrave;", "&eacute;", "&ecirc;", "&euml;", "&igrave;", "&iacute;",
"&icirc;", "&iuml;", "&eth;", "&ntilde;", "&ograve;", "&oacute;",
"&ocirc;", "&otilde;", "&ouml;", "&divide;", "&oslash;", "&ugrave;",
"&uacute;", "&ucirc;", "&uuml;", "&yacute;", "&thorn;", "&yuml;");

  return str_replace($trans_tbl[$cs_from],  $trans_tbl[$cs_to], 
$string);
}

$string = recode_charset('�������','ASCII','HTML');

will produce &Atilde;&atilde;&Ucirc;&ucirc;&Otilde;&otilde;&THORN;

but &Auml;&auml;&Uuml;&uuml;&Ouml;&ouml;&szlig; is correct.

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the

Thank you for your interest in PHP.

Sorry for bothering (and for my writing errors).

There actually is another function in PHP that has the
behaviour that I expect: strtr(str, arr)

$vReplace['@gill'] = '@doubleyou';
$vReplace['@doubleyou'] = '@bates';

$sSubject = "@gill @doubleyou is not my friend";
$sResult = strtr($sSubject, $vReplace);

echo $sResult; 
// will output "@doubleyou @bates is not my friend"
