PHP Smarty 返回页面内容方法

使用$smarty->display()时是没有办法将页面以字符串的形式返回的。

查看smarty源码发现display其实是调用的$smarty->fetch(),发现一个$diaplay参数,true时打印页面,false时返回字符串。直接贴源码(...为省略的逻辑代码)

public function fetch($template = null, $cache_id = null, $compile_id = null, $parent = null, $display = false, ...)    {        ...        // display or fetch        if ($display) {            ...            echo $_output;            return;        } else {            ...            return $_output;        }    }

所以使用如下语法可以返回页面内容

$smarty->fetch('xxx');
