Buen día
el caso es el siguiente, tengo un servidor con CentOS 5.6 instalado con php y mysql y funcionando a la perfección, he instalado un nuevo servidor pero con CentOS 6.2 php y mysql y en este ultimo al pasar la carpeta de las paginas que tenia creadas en el primero, estas dejan de funcionar, una simple linea de codigo (print("Texto <BR>" y este no visualiza lo que debe de escribir, alguien sabe a que se debe este error?

Saludos y de ante mano muchas gracias!!

Verifica que esté instalado el paquete php. Si sólo instalaste el paquete php-mysql, tiene un error en el spec que no incluye al paquete php como dependencia.

Tengo instalado el php y el php-mysql ya que un script de php que me hace validación si corre, el problema solo se presenta en la interfas web que no me reconoce la mexcla entre php y html
Esta es la salida que tengo con rpm -q
[root@server]# rpm -q php
php-5.3.3-14.el6_3.i686
[root@server]# rpm -q php-mysql
php-mysql-5.3.3-14.el6_3.i686
[root@server]#

Verifica componentes:



¿Que contiene /etc/httpd/conf.d/php.conf?



¿Está habilitada la política httpd_builtin_scripting de SELinux?



Si está inactiva, ejecuta:



Por favor, publica un extracto de /var/log/httpd/error_log y de /var/log/audit/audit.log.

Gracias por responder, aquí estan las salidas:
rpm -V php

De ante mano muchas gracias por estar respondiendo, en efecto fue a causa de la actualización en el php.ini anterior tenia "short_open_tag = On" y en el nuevo server esa misma etiqueta la tenia como "short_open_tag = Off" buscando un poco mas encontre ese detalle en esta pagina "http://www.samuelaguilera.com/archivo/parse-error-syntax-error-unexpected-end.xhtml"

Saludos!!
