PHP Smarty Return Page content method

There is no way to return a page as a string when using $smarty->display ().

View Smarty Source Discovery display is actually called the $smarty->fetch (), found a $diaplay parameter, true when printing the page, False when the return string. Direct Paste Source (... Logical code to omit)

Public function fetch ($template  = null,  $cache _id = null,  $compile _id  = null,  $parent  = null,  $display  = false,&nbsp ...)     {        ...         // display or fetch        if  ($ Display)  {            ...             echo $_output;             return;        } else {             ...             return $_output;         }    }

So use the following syntax to return to the page content

$smarty->fetch (' xxx ');
