Una pregunta, como centro esto:
Código PHP:
<?
$content = '
<script type="text/javascript"><!--
google_ad_client = "xxxxx";
google_ad_width = 120;
google_ad_height = 240;
google_ad_format = "120x240_as";
google_ad_type = "text";
google_ad_channel ="";
google_page_url = document.location;
google_color_border = "DFE6EF";
google_color_bg = "DFE6EF";
google_color_link = "2A63C1";
google_color_url = "C00000";
google_color_text = "000000";
//--></script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>';
?>
Gracias
