loadTemplateFile() -- Loads a template file.


require_once 'HTML/Template/Sigma.php';

mixed HTML_Template_Sigma::loadTemplateFile (string $filename [, boolean $removeUnknownVariables = TRUE [, boolean $removeEmptyBlocks = TRUE]])


Loads a template file. If caching is on, then it checks whether a "prepared" template exists. If it does, it gets loaded instead of the original, if it does not, then the original gets loaded and prepared and then the prepared version is saved. addBlockfile() and replaceBlockfile() implement quite the same logic.


string $filename


boolean $removeUnknownVariables

remove unknown/unused variables?

boolean $removeEmptyBlocks

remove empty blocks?

Return value

return SIGMA_OK on success, error object on failure
