To get a more meaningful "did you mean", I use metaphones on the suggestion list, this helps to insure that the word is one that "sounds" closer to the word spelled wrong.

<?php
function spellcheck ( $string ) {
   $words = split(' ',$string);
   $misspelled = $return = array();
   pspell_config_create("en",PSPELL_NORMAL);
   $int = pspell_new('en');
   foreach ($words as $value) {
       $check = preg_split('/[\W]+?/',$value);
       if (($check[1] != '') and (strpos("'",$value) > 0) ) {$check[0] = $value;}
       if (($check[0] + 1 == 1) and (!pspell_check($int, $check[0]) )) {
           $res  .= '<SPAN class="misspelled" style="color:#FF0000; font-weight:bold;">' . $value . ' </SPAN> ';
           $poss = pspell_suggest($int,$value);
           $orig = metaphone($value);
           foreach ($poss as $suggested)
           {
                 $ranked[metaphone($suggested)] = $suggested;
           }
           if ($ranked[$orig] <> '') {$poss[1] = $ranked[$orig];}
          
           $res2  .= '<SPAN style="color:#CC8800; font-weight:bold">' . $poss[1] . ' </SPAN> ';

       } else {
       $res .= $value . ' ';
       $res2 .= $value . ' ';
       }
   }

   $n[1] = $res;
   $n[2] = $res2;
   return $n;
}
?>

this helps to correct for the fact that pspell_suggest's first idea of a replacement is just the first in the alphabet.

It seems if you are trying to do something similar to the Google 'Did you mean:' suggestions and are selecting the first word given by the pspell_suggest() function, then it will not work well with custom dictionaries and replacements. Take the following code for example:

<?php
    $pspell_config = pspell_config_create("en");
    pspell_config_personal($pspell_config, "/home/user/public_html/custom.pws");
    pspell_config_repl($pspell_config, "/home/user/public_html/custom.repl");
    $pspell_link = pspell_new_config($pspell_config);

    $words = preg_split ("/\s+/", $query);
    $ii = count($words);

    global $spellchecked;
    $spellchecked = "";
   
    for($i=0;$i<$ii;$i++){

        if (pspell_check($pspell_link, $words[$i]))
        {
            $spellchecked .= $words[$i]." ";
        }
        else
        {
            $erroneous = "yes";
            $suggestions = pspell_suggest($pspell_link, $words[$i]);
            $spellchecked .= $suggestions[0]." ";
        }
    }
    if($erroneous == "yes")
    {
        echo "Did you mean: <i>".$spellchecked."?";
    }
    else
    {
        echo $spellchecked . " is a valid word/phrase";
    }
?>

This works fine most of the time, and gives suggestions to what you meant when inserting a spelling mistake with most inputs. However, if you specify a custom replacement and then search for the misspelt word that you specified, then if it is not the first returned suggestion it wont be used in the 'Did you mean' end result. What you need to do is open up the custom dictionary using fopen and fread, and then for each of the suggested words, check if they are in the dictionary. If the suggested word is in the custom dictionary then use it in the 'Did you mean' part, if not, discard it and try the next. Hope this helps anyone who comes across this problem with trying to get more accurate suggestions.
