<div class="form">
<form action="index_ajax.php" name"form1" method="get">
<div class="ausu-suggest">
<input type="text" size="9" value="" name="telefono" id="telefono" autocomplete="off" />

</div>
 </div>

$result = mysql_query($query); 

        $dataList = array(); 

        while ($row = mysql_fetch_array($result)) 
        { 
        $toReturn   = $row['telefono']; 
        $dataList[] = '<li><a href="#">' . htmlentities($toReturn) . '</a></li>';      
        } 
     if (count($dataList)>=1) 
     
        {  
            $dataOutput = join("\r\n", $dataList); 
            echo $dataOutput; 
             
        } 
        else 
        { 
            echo '<li><a href="#">No Results</a></li>';
