Token: use in PHP code, getting values and labels.

Maybe I can help a tiny bit, and I hope it is Ok to do this in this place.
I am about in the same place you are, but I did discover 1/2 of what you are asking. this works, I am using it, it is not a guess. But it probably took 4 hours to just find, this part of it.
So I can't tell you if it is correct, good code or just lucky, but it works.

// Run site creation script, then redirect to completed page
// this is the start of the code, no magic stuff happens before this.
$var = token_replace('[current-user:name]', array('current-user' => $user));
//strip out spaces from name if there are any
$var=str_replace(" ", "", $var);
$var2 = token_replace('[current-user:mail]', array('current-user' => $user));
$var3 = "aberdeen";
$var4 = token_replace('[commerce-order:order-number]', array('commerce-order' => $order));
// run the external script
print exec("sudo makesite_simple.sh $var $var2 $var3 $var4");
// return the user to the "completion" page
header( 'Location: http://www.xxxxx.ca/node/7' ) ;
exit();

Hello friends,

when I create a new content, I want the "title" (the mandatory fixed field) to have a specific form and to be generated automatically based on the filled fields.

That's why I've set a few nodes in "AUTO NODE LABEL" that generate my page title. It looks roughly like this: [node: field_per_degree_before_n] [node: field_per_first_name] [node: field_per_surname] [node: field_per_degree_after_n], [node: field_per_profession], [node: field_per_narozen]

Between some of that tokens I want to add comma "," but I want the comma to be generated only if token has value (e.c. the field of that token is filled). If not, then I do not want to generate this comma. The reason is that in the case of some no-filled fields I do not want to have commas generated, for example, the title incorrectly generated could look like this:

Ing. Kamil Blazek, , student,

correctly should look like this: Ing. Kamil Blazek, student

Why should be generated like this? Because I left empty field "field_per_degree_after_n" and "field_per_narozen" - so tokens are not added, but the commas yes, because they are as fixed text.

How can I ensure something like this: if "field_per_degree_after_n" haas value Than "," and if "field_per_narozen" has value Than ","?

I do not know PHP codes, so if there is some tool or if someone have solved already this php, could you help me and send me it? Also I have information to use function "implode". Also I do not know how. I am lost...

Please for help.
Thank you

Solved:

[node:field_example]

if ('[node:field_example]')
{print 'comma after text';}
else {print '';} 

Someting similar to above worked for me.

$var=[token_variable];

I was trying to use
in views and got to work with one of the views fields.

To update:
The format above works on views, but not in rules, I have to use token_replace

#4 made my day, thanks mates
