accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab 
illo inventore veritatis et quasi architecto beatae vitae dicta sunt 
explicabo. Nemo enim ipsam voluptatem quia voluptas sit aspernatur aut 
odit aut fugit, sed quia consequuntur magni dolores eos qui ratione 
voluptatem sequi nesciunt. Neque porro quisquam est, qui dolorem ipsum 
quia dolor sit amet, consectetur, adipisci velit, sed quia non numquam 
eius modi tempora incidunt ut labore et dolore magnam aliquam quaerat voluptatem. 
Ut enim ad minima veniam";
// your page id to display full content
$page_id = 456;
// your page file to display full content
$link = "page.php";
// limit content character
$limit = 100;
// Called readMore() function to convert full content to read more link
echo readMore($content,$link,"id",$page_id, $limit, $limit);
?>

$content = substr($content,0,$limit);
