你不應該混用PHP和Smarty，所以你應該在PHP中做你需要的，併爲Smarty賦值。那麼你根本不需要使用{php}標籤。 Smarty用於顯示數據，並將Smarty與Smarty混合使得使用Smarty沒有多大意義。
但是如果你真的需要使用Smarty的模板PHP代碼，你應該改變：
$app = new \Slim\Slim(array(
'view' => new \Slim\Views\Smarty()
));
到
$app = new \Slim\Slim(array(
'view' => new \Slim\Views\SmartyBC()
));
，但我真的不建議使用內部Smarty模板PHP
編輯 - SMARTYBC視圖不在SLIM框架中存在，因此我們必須創建它
儘管我從來沒有使用Slim框架，但我決定進一步研究。由於SmartyBC在Slim視圖中不存在，我們必須手動創建它。
在你需要創建SmartyBC.php與內容文件修身\瀏覽目錄：

事實上，你必須簡單複製從Smarty.php查看內容和更改所有的Smarty到SmartyBC。而已！
的index.php文件應該是這樣的：
<?php
require 'Slim/Slim.php';
\Slim\Slim::registerAutoloader();
$app = new \Slim\Slim(array (
'view' => new \Slim\Views\SmartyBC()
)
);
$view = $app->view();
$view->parserDirectory = dirname(__FILE__) . '/smarty';
$view->parserCompileDirectory = dirname(__FILE__) . '/compiled';
$view->parserCacheDirectory = dirname(__FILE__) . '/cache';
$view->setTemplatesDirectory(dirname(__FILE__) . '/smarty/templates');
$app->get(
'/',
function() use ($app) {
$app->render('index.tpl', array('test' => 'User'));
}
);
$app->post(
'/post',
function() {
echo 'This is a POST route';
}
);
$app->put(
'/put',
function() {
echo 'This is a PUT route';
}
);
$app->patch('/patch', function() {
echo 'This is a PATCH route';
});
$app->delete(
'/delete',
function() {
echo 'This is a DELETE route';
}
);
$app->run();
您不必手動，包括在這裏SmartyBC.class.php，你在你的代碼一樣。當然，這只是示例代碼和最小代碼（用於Slim框架和添加的Smarty視圖）。
模板文件：
{$test}, hello world and {php} echo "hello world from php"; {/php}
輸出是：
User, hello world and hello world from php
所以正是你想要達到的目標。
但是我想提醒你，這不是混合你的PHP和模板的最好方法。即使在Smarty文檔中，您也可以閱讀：
{php}標記已從Smarty中棄用，不應使用。將 代替PHP腳本或插件函數。
我想這和它不工作，看起來像在 – Uchenna
我已經添加了完整的解決方案，我的回答是 –
該解決方案爲你工作苗條意見不包括SmartyBc？ –
