模板类中的PHP

Question

我目前正在研究broculus的模板类。 现在我想使用该类将PHP安装到模板中。不幸的是，我目前失败了。 通过评估它肯定不是我已经建立。现在我想问你是否有一个想法可以轻松解决问题。

在该代码中我希望得到一个变量，它是PHP代码的价值。 该代码将被执行。

例子： $row_1->content = '$name = 'Pagetitle'; echo $name;';

$row->content包含PHP和完整的脚本。

$layout = new Template("template/layout.tpl"); 
$layout->set("title", $sitename); 
$layout->set("content", eval($row_1->content));

我发现使用ob_start的溶液。在panel.php我通过eval执行PHP代码。

// Ausgabepuffer an 
ob_start(); 
// Skript ausführen 
$_GET['panel'] = 1; 
include('panel.php'); 
// Ausgabe aus Puffer holen 
$inhalt = ob_get_contents(); 
// Puffer schließen 
ob_end_clean(); 

//Layout holen 
$layout = new Template("template/layout.tpl"); 
$layout->set("title", $sitename); 
$layout->set("content", $inhalt); 

您对此有何看法？

Es war keine wirklicheLösung，wie es sich herausgestellt hat。 Versuche nun die Template Engine von Smarty zu nutzen。 Weißjemand wie ich dort PHP im Template darstellen kann？

require '../libs/Smarty.class.php'; 

$smarty = new Smarty; 

$smarty->compile_check = true; 
$smarty->debugging = false; 

$smarty->assign("Name","Fred Irving Johnathan Bradley Peppergill"); 
$smarty->assign("Menu","MENU"); 
$smarty->assign("Content", "echo 'Testinhalt soll angezeigt werden.'; "); 


$smarty->display('index.tpl');
