utilizo este código en varias páginas de la siguiente forma:
Código PHP:
<? include ("p_sesion.php"); ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<? include ("p_seguridade.php"); ?>
<html xmlns="http://www.w3.org/1999/xhtml" lang="gl" xml:lang="gl">
<head profile="http://geotags.com/geo">
pero me sale esto:
Código:
Warning: Cannot modify header information - headers already sent by (output started at /data/members/free/tripod/es/a/p/i/apintega/htdocs/index.php:1) in /data/members/free/tripod/es/a/p/i/apintega/htdocs/foro/includes/sessions.php on line 258
