-This tells Smarty how to handle PHP code embedded in the templates.
-There are four possible settings, the default being
-`Smarty::PHP_PASSTHRU`. Note that this does NOT affect php code within
-[`{php}{/php}`](#language.function.php) tags in the template.
-
--   `Smarty::PHP_PASSTHRU` - Smarty echos tags as-is.
-
--   `Smarty::PHP_QUOTE` - Smarty quotes the tags as html entities.
-
--   `Smarty::PHP_REMOVE` - Smarty removes the tags from the templates.
-
--   `Smarty::PHP_ALLOW` - Smarty will execute the tags as PHP code.
-
-> **Note**
->
-> Embedding PHP code into templates is highly discouraged. Use [custom
-> functions](#plugins.functions) or [modifiers](#plugins.modifiers)
-> instead.
