preg_replace on array with "E (PCRE_DOLLAR_ENDONLY)" modifier

Hi, I'm having problems stopping preg_replace from losing $ signs and following text when replacing with array variables. I am trying to use the E modifier and keep getting: "Warning: Unknown modifier 'E' in script.WEB.php3 on line 413" $template=array( "/({PAGETOP})/E", "/({PAGEMIDDLE})/E", "/({PAGEBOTTOM})/E" ); $pagevars=array( "PAGETOP" => $pagetop, "PAGEMIDLE" => $pagetop, "PAGEBOTTOM" => $pagenavbar, ); Text from assorted sources such as database records or external files are placed into the variables $pagetop ... $page = "{PAGETOP}{PAGEMIDDLE}{PAGEBOTTOM}"; $page = preg_replace($template,$pagevars,$page); Other modifiers seem to be accepted. Any help appreciated.
