Question: I need to the extract the content from the string "%body" to first paragraph. Am using

Instead of Regex, try the PHP explode() Function[^]

<?php
$line = "%body
The family is a central socialization context from early childhood
behavior \cite{dishi-sto2007,hengg-etal1998,johns-etal2005}.

Family management becomes more challenging for parents during the 
transition from middle childhood to adolescence. Typically developing ";

$array = explode("\n\r", $line);
echo $array[0];

?>
