Replace HTML paragraphs with breaks, assuming the content is in a <p>-wrapper that we want to keep.

<?php
 $bodyText = $content['field_body']; // This is incorrect, the structure is different (use var_dump to figure it out)
 
 $ptOne = substr($bodyText, 0, 3); // <p> - 0, 1, 2
 $ptTwo = substr($bodyText, 3, -4); // text inside wrapper
 $ptThree = substr($bodyText, -4); // </p> - 0, 1, 2, 3
 
 $newcontent = preg_replace("/<p[^>]*?>/", "", $ptTwo);
 $newcontent = str_replace("</p>", "<br /><br />", $newcontent);
 
 $newcontent = $ptOne . $newcontent . $ptThree;
 
 print render($newcontent);
