As of Smarty 3.1 the {php} tags are only available from SmartyBC.

Find the file smarty.class.phpin your host directory
smarty.class.php在您的主机目录中找到该文件
Go to smarty.class.php
去 smarty.class.php
Edit var $php_handling = SMARTY_PHP_ALLOW;
编辑var $php_handling = SMARTY_PHP_ALLOW;
Save the file in server.
将文件保存在服务器中。
Now you may add php in tpl file as <?php ....code.... ?>

You may have seen the documentation, but you have missed {php}:
您可能已经看过文档，但您错过了{php}：
The {php} tags allow PHP code to be embedded directly into the template. They will not be escaped, regardless of the $php_handling setting. This is for advanced users only, not normally needed and not recommended.
{php} 标签允许将 PHP 代码直接嵌入到模板中。无论 $php_handling 设置如何，它们都不会被转义。这仅适用于高级用户，通常不需要也不推荐。
Emphasis mine, source: http://www.smarty.net/docsv2/en/language.function.php.tpl
强调我的，来源：http: //www.smarty.net/docsv2/en/language.function.php.tpl
Note that putting PHP in template code is the easiest way to shoot yourself in the foot - the main purpose of Smarty is to separate PHP code and HTML templates. In other words, the mere fact of using this tag is a serious red flag; in most cases, it is possible to fix the underlying issue, and avoid PHP inside the template altogether.
请注意，将 PHP 放在模板代码中是最简单的方法——Smarty 的主要目的是将 PHP 代码和 HTML 模板分开。换句话说，仅仅使用这个标签的事实就是一个严重的危险信号；在大多数情况下，可以解决根本问题，并完全避免在模板中使用 PHP。

Have you tried to enable error reporting?
您是否尝试过启用错误报告？
error_reporting(E_ALL);
ini_set("display_errors", true);
