I am not sure of a PHP version of this script, but it shouldn't be too difficult to create a similar script. Basically you would need a MySQL database backend to store the information and ample space to store the photos..
the tables would be setup similar to this:
vote table -- would contain the votes for each picture (would contain an association to the personal table, possibly the IP address of the voter (so they won't vote twice on a person), & their vote)
personal table -- would contain the information for each individual picture (age, picture, text, email address, etc..)
Afterwards, you could simply create a form that would allow new submissions (PHP has built in functionaility to make file uploads (for the pictures) extremely easy)and create a page that would allow people to vote on the individuals.
