[pmwiki-users] Help with preg_replace/e

Dear PmWiki Users,

In trying to convert UpdateForm to be PHP 5.5 compatible, I ran into the last line of the original recipe -- The last three lines are:

//exit code copied bodily from forms.php
  $FmtV['$UpdateFormArgs'] = implode(' ', $attr);
  $out .= FmtPageName($opt[':html'], $pagename);
  return preg_replace('/<(\\w+\\s)(.*)$/es',"'<$1'.Keep(PSS('$2'))", $out);

Now clearly this is from an old version of forms.php, but I don't really understand  the expression to be evaluated.  Can you help?
