How are you. Hope Fine...

I am facing a problem with the following code. The strtr function isn't working. It doesn't output anything...

if ($translate == "DrChatrikWeb") {
$convertarray = array(
"~" => "~",
"!" => "!",
"@" => "@",
"#" => "#",
"$" => "$",
"%" => "%",
"^" => "^",
"&" => "&",
"*" => "*",
"(" => "(",
")" => ")",
"_" => "_",
"+" => "+",
"`" => "`",
"1" => "1",
"2" => "2",
"3" => "3",
"4" => "4",
"5" => "5",

);
$string = strtr($texttoreplace, $convertarray);
echo $string;
}

The array is in Punjabi i.e. is a indic language...

This code is working perfectly...

$repp = array(
        "<br />" => " <br> ",
        " ," => " <punc>,</punc> ",
        " ." => " <punc>.</punc> ",
        " /" => " <punc>/</punc> ",
        " \\" => " <punc>\\</punc> ",
        " !" => " <punc>!</punc> ",
        " ?" => " <punc>?</punc> ",
        " :" => " <punc>:</punc> ",
        " ;" => " <punc>;</punc> ",
        " \"" => " <punc>\"</punc> ",
        " '" => " <punc>'</punc> ",

        " *" => " <punc>*</punc> ",
        " _" => " <punc>_</punc> ",
        " =" => " <punc>=</punc> ",
        " +" => " <punc>+</punc> ",
        " |" => " <punc>|</punc> ",
        " -" => " <punc>-</punc> ",

        ":" => "<> <punc>:</punc> ",
        ";" => "<> <punc>;</punc> ",

    );
    $repps = strtr($texttoreplace, $repp);
    echo $repps;

Plzz Help..

it's this pair causing the issue, remove it and it works

"" => ",",

as the manual says:

If replace_pairs contains a key which is an empty string (""), FALSE will be returned.
