Puppet Cannot start php service that is defined in a puppet manifest

Question

I have written a puppet manifest to install php , Here's the /etc/puppet/modules/php/manifests/init.pp

class php {

  $phpname = $osfamily ? {
    'Debian'    => 'php5',
    'RedHat'    => 'php',
    default     => warning('This distribution is not supported by the PHP module'),
  }

  package { 'php':
    name    => $phpname,
    ensure  => present,
  }

  package { 'php-pear':
    ensure  => present,
  }

  service { 'php-service':
    name    => $phpname,
    ensure  => running,
    enable  => true,
  }

}
I have added include php to the hosts in my sites.pp file.
The catalog is applied successfully on my agent except the fact that I am unable to start the php service. How do I ensure that the service is started successfully?
