[SOLVED] standard_error on foreach loop

[omardealo]

Hello ,

i make a plugin [stop new thread if That it contains Banned words]
every thing is okay , but when i try print all Banned words Written by User , but Do not print all the words, only the last word .
i Used the code in a php file with ECHO to print and working good , but in plugin i have problem with standard_error Do not print, but only the last value . so Where the problem ?

PHP Code:

$bwords = explode("|", $vbulletin->options['banwords_wordslist']); 
$string = $vbulletin->GPC['message'];
$matches = array();
$matchFound = preg_match_all(
                "/\b(" . implode($bwords,"|") . ")\b/i", 
                $string, 
                $matches
              );
if ($matchFound)
{
  $words = array_unique($matches[0]);
  foreach($words as $word)
  {
     eval (standard_error( "Banned Words : <li>" . $word . "</li>")); 
  }
}
