I have writed this function:

function news_array()
 {
 $sql = "SELECT * FROM content WHERE home=1";
    $query = mysql_query($sql);
    $i = 0;
            while($row = mysql_fetch_array($query)){
                $row_array[$i] = 
                array(
                    TITLE => $row['title'],
                    ABSTRACTT => $row['abstract'],
                    BODY => $row['body'],
                    ID => $row['conID']
                );
               $i++; 
            }  
   return $row_array;
   }

When using this function like this:

<?php
  $row_array = news_array();
  for($i = 0 ; $i < count($row_array) ; $i++){
   echo $row_array[$i][TITLE];
 }

 ?>

There no output in html. What is wrong in my function? Thanks in advance
