PHPTAL automatically calls methods in TAL expressions. If you use ORM it  
should be quite simple, e.g. if you have Employee object that has  
getDepartment() method that returns Department object:

<li tal:repeat="employee employees"  
tal:content="employee/getDepartment/name"/>


Alternatively you can call PHP functions using php: prefix in expressions:

<li tal:repeat="employee_row employees_array">
   <tal:block tal:define="department  
php:get_department_row(employee_row['department_id'])"  
tal:content="department/name"/>
