# phpcs --version
PHP_CodeSniffer version 1.3.3 (stable) by Squiz Pty Ltd. (http://www.squiz.net)
# 

Trying to do this:

phpcs --tab-width=2 includes/json/item/categorie.php 
FOUND 29 ERROR(S) AND 3 WARNING(S) AFFECTING 24 LINE(S)

Doesn't work. This doesn't work too:

phpcs includes/json/item/categorie.php --tab-width=2
FOUND 29 ERROR(S) AND 3 WARNING(S) AFFECTING 24 LINE(S)

If I indent the file with 4 spaces (which I don't want):

phpcs --tab-width=2 includes/json/item/categorie.php 
FOUND 4 ERROR(S) AND 3 WARNING(S) AFFECTING 17 LINE(S)
phpcs --tab-width=4 includes/json/item/categorie.php 
FOUND 4 ERROR(S) AND 3 WARNING(S) AFFECTING 17 LINE(S)
phpcs --tab-width=50 includes/json/item/categorie.php 
FOUND 4 ERROR(S) AND 3 WARNING(S) AFFECTING 17 LINE(S)
phpcs includes/json/item/categorie.php --tab-width=50 
FOUND 4 ERROR(S) AND 3 WARNING(S) AFFECTING 17 LINE(S)

So it's totally ignored. It this a bug?

Sorry, my bad:

# phpcs --help
Usage: phpcs [-nwlsapvi] [-d key[=value]]
        ...blabla...
        <tabWidth>    The number of spaces each tab represents
        ...blabla...

This means "when there's the tab character, how many spaces does it represent".

There's nothing to do with indentation of "4" which seems to be hard-coded.
