Constructor & Destructor Documentation

__construct()

Twig_Environment::__construct	(	Twig_LoaderInterface	$loader = null,
			$options = array()
	)

Constructor.

Available options:

• debug: When set to true, it automatically set "auto_reload" to true as well (default to false).
• charset: The charset used by the templates (default to UTF-8).
• base_template_class: The base template class to use for generated templates (default to Twig_Template).
• cache: An absolute path where to store the compiled templates, a Twig_Cache_Interface implementation, or false to disable compilation cache (default).
• auto_reload: Whether to reload the template if the original source changed. If you don't provide the auto_reload option, it will be determined automatically based on the debug value.
• strict_variables: Whether to ignore invalid variables in templates (default to false).
• autoescape: Whether to enable auto-escaping (default to html):
  • false: disable auto-escaping
  • true: equivalent to html
  • html, js: set the autoescaping to one of the supported strategies
  • name: set the autoescaping strategy based on the template name extension
  • PHP callback: a PHP callback that returns an escaping strategy based on the template "name"
• optimizations: A flag that indicates which optimizations to apply (default to -1 which means that all optimizations are enabled; set it to 0 to disable).

Parameters

Twig_LoaderInterface	$loader
array	$options	An array of options
