I have no idea why it's in the state it is in now, but surely the logical tag for PHP 5.2 specific problems should be php5.2 and not php52?
Indeed, there are no php53 questions out there but instead php5.3. No synonym exist for that too.
Edit: Of course we could also go with what sth suggested and go with php-5.2 and php-5.3, but that would require two synonyms/tag merges.
This makes them consistent in relation to each other and with other tag-version.minor tags in the system.
php-5.2 would be even better.
