You can define global variable in twig template like:
# app/config/config.yml
twig:
# ...
globals:
ga_tracking: UA-xxxxx-x
Or it in PHP template like:
// app/config/config.php
$container->loadFromExtension('twig', array(
// ...
'globals' => array(
'ga_tracking' => 'UA-xxxxx-x',
),
));
And then use it in twig:
<p>The google tracking code is: {{ ga_tracking }}</p>
or in PHP template:
<p>The google tracking code is: <?php echo $ga_tracking; ?></p>

Thanks but this doesn't work because when you said: Or it in PHP template like:... this is tod efine global variable for twig template but using php languaje y config.php instead of YAML like in the first one. But both are for twig template, see that in code is written: 'twig'

Only in PHP template doesn't exist the variable
You have to define the variable in your config file, for example:
# app/config/config.yml
parameters:
foo: "bar"
and then you can access it from your PHP templates:
<?php echo $view->container->parameters['foo']; ?>

There has to be a problem somewhere in your code, it works for me just fine. Do you have the php templating engine allowed? Have you tried to clear the cache? Are you accessing the right parameter name? Maybe you have set different parameters for prod/dev environment?

Yes thanks, I don't know where is the problem, I'll search in my code, thanks
