smarty修改嚣中使用php函数

quoteModifiers can be autoloaded from your $plugins_dir (also see: Naming Conventions) or can be registered explicitely (see: register_modifier). Additionally all php-functions can be used as modifiers implicitely. (The @count-example above actually uses php's count-function and not a smarty-modifier). Using php-functions as modifiers has two little pitfalls: First: Sometimes the order of the function-parameters is not the desirable one ({"%2.f"|sprintf:$float} actually works, but asks for the more intuitive {For example: $float|string_format:"%2.f"} that is provided by the Smarty distribution). Second: with $security turned on all php-functions that are to be used as modifiers have to be declared trusted in the $security_settings['MODIFIER_FUNCS']-array.

在 大家手中的smarty手册大都是来自PHP中文社区。中英对照，译的很好。可是，上面一段也在其中，却没有翻译。估计很多人和我一样，只看中文了，忽略 了这个相当重要的一段。我是在smarty.php.net上看到这段的，回过头来发现手册中竟然也有，竟然没有翻译。

扯远了。

这一段明确说明在modifier 中是可以使用php 函数的。

比如有一array 传给了smarty
$arr = array('a', 'b', 'c',);

我想输出这样的形式：
a,b,c;
就可以这样写
{','|implode:$arr};


输出<td>a</td><td>b</td><td>c</td>
可以这样写
<td>{"</td><td>"|implode:$arr}</td>

和foreach or section比起来是不是很爽。

希望对不知道的弟兄们有帮助。
