Undefined Variable record: (in a path)/filename.php

$sql= "select * from demo table";
$handler=mysql_query($sql);
while($data=mysql_fetch_assoc($handler)){
$record[]=$data
}
<?php for($i=0;$i<count($record);$i++) ?>

You should initialize $record before the loop, in case the query fails.

$record=array();

write this before while loop.
