98 Overriding a Template that also extends itself
103 * *Inheritance*: A template *extends* a parent template and overrides some
107 template it finds in a list of configured directories; a template found in a
108 directory *replaces* another one from a directory further in the list.
110 But how do you combine both: *replace* a template that also extends itself
111 (aka a template in a directory further in the list)?
125 You can replace this template by putting a file with the same name in

395 Using a Database to store Templates
398 If you are developing a CMS, templates are usually stored in a database. This
399 recipe gives you a simple PDO template loader you can use as a starting point
402 First, let's create a temporary in-memory SQLite3 database to work with::
415 We have created a simple ``templates`` table that hosts two templates:
418 Now, let's define a loader able to use this database::
