评估HTML&的PHP Eval；的PHP [英] PHP Eval that evaluates HTML & PHP

问题描述

我搞砸了模板，遇到了一种情况，我需要向浏览器回显包含html&的模板.的PHP.如何评估PHP并将其发送到浏览器?

I'm messing around with templating and I've run into a situation where I need to echo to the browser a template that contains html & php. How do I evaluate the PHP and send it to the browser?

所以这是一个例子(main.php):

So here's an example (main.php):

    <div id = "container">
        <div id="head">
            <?php if ($id > 10): ?>
                <H3>Greater than 10!</H3>
            <?php else: ?>
                <H3>Less than 10!</H3>
            <?php endif ?>
        </div>
            </div>

然后在template.php中:

And then in the template.php:

   <?php
           $contents; // Contains main.php in string format
           echo eval($contents); // Doesn't work... How do I do this line??
   ?>

我的模板还允许您从控制器Smarty样式注入数据.将输出缓冲区允许我执行此操作，然后评估我的php.理想的情况是，它首先执行代码，然后首先评估所有标记，然后运行php.这样，我就可以使用控制器发送的数据来创建循环和内容.

So maybe a more complete example: 
    <div id = "container">
            <div id = "title">{$title}</div> <!-- This adds data sent from a controller -->
            <div id="head">
                <?php if ($id > 10): ?>
                    <H3>Greater than 10!</H3>
                <?php else: ?>
                    <H3>Less than 10!</H3>
                <?php endif ?>
            </div>
    </div>

谢谢！

推荐答案

如果您尝试使用混合HTML/PHP字符串(例如从数据库访问)，可以这样做:

In case you are trying to do this with a string of mixed HTML/PHP (like from a database, as I was), you can do it this way:

eval(' ?>'.$htmlandphp.'<?php ');
