Try this php code:

<?php
   $str = "T I G R U S FOO and Drezga d . o . o . New York";
   $out = preg_replace('~(\b.)\s~', "\\1", $str);
   var_dump($out);
?>

OUTPUT

string(38) "TIGRUSFOO and Drezga d. o. o. New York

UPDATE

<?php
   $str = "T I G R U S FOO and Drezga d . o . o . New York N Y";
   $s = preg_replace('~((?<=^[^\s])|(?<=\s[^\s]))\s(?=[^\s](\s|$))~', "", $str);
   var_dump($s);
?>

OUTPUT

string(40) "TIGRUS FOO and Drezga d.o.o. New York NY"

?>

That's not possible, unfortunately. There is no easy way to distinguish single-space word boundaries from extraneous single-spaces between a word's characters.

EDIT: Retracted -- I made the assumption that the replacement would need to properly handle (i.e. keep separate) words that are actually one character long.

The following works. 

$string = "T I G R U S FOO and Drezga d . o . o . New York";

$words = explode(" ", $string);

$output = array();
$temp_word = "";
foreach($words as $word)
{
    if (strlen($word) == 1)
    {
        $temp_word .= $word;
    }
    else
    {
        if ($temp_word != "")
        {
            $output[] = $temp_word;
            $temp_word = "";
        }
        $output[] = $word;
    }
}

$output = implode(" ", $output);
echo $output;

Outputs: "TIGRUS FOO and Drezga d.o.o. New York"
