Word count like function Ver.1.0! This function can count your input text
and display only part of it (like a description) without cutting words in half

  function smart_text ($text_input_var[string] ,text_length[int]) 
  { 
      $strip_content=stripslashes($content); 
      $all_content=strlen("$strip_content"); 

      $standard_content=substr($strip_content ,$text_length); 
      $compare=stristr($standard_content ," "); 
      $minus_content=strlen("$compare"); 
                 
      $result_content=$all_content-$minus_content; 
      $display_content=substr($strip_content ,0, $result_content); 
                 
      $striped_content=stripslashes($display_content);   
      echo nl2br($striped_content); 
  } 

For example i insert a 300 words test but only want about 3 rows of it to be displayed 
without cutting words in half. 
                 
function smart_text($text,200) 

Displayed result will be the first 200 letters of the text plus the letters till the first space 
char.

Short text sample from long text articles

When you want to show a snippet of text for an article but dont want to cut off words in the middle, use this little function. 

 0)) 
    { 
        $split_text = explode(" ", $source_text, $word_count); 
        if (sizeof($split_text) < $word_count) 
        { 
            $long_enough = FALSE; 
        } 
        else 
        { 
            array_pop($split_text); 
            $source_text = implode(" ", $split_text); 
        } 
    } 
    return $long_enough; 
} 

// sample use 
$long_text="a b c d e f g h i j k l m n o p q r s t u v w x y z"; 
$short_text=$long_text; 
$more_text_available=shortenText($short_text, 20); 

echo $short_text; 
if($more_text_available) 
{ 
  echo 'more...'; 
} 

?>
The text is shortened to the required word length. The returned value tells us if the original text is shorter than the required word length. This can then be used to determine if we want to use a link or script to display the full article.
