将文本输入解释为PHP [英] Interpret text input as PHP

问题描述

我想让用户测试我的PHP类，其中包括裁剪和调整图像大小.

I want to let users test out a PHP class of mine, that among other things crops and resizes images.

我希望他们在文本字段中编写PHP代码，发送表格，然后运行他们的代码.我该怎么办?

I want them to write PHP code in a text field, send the form, and then their code will be run. How can I do this?

还是让用户(任何人)演示PHP类的其他安全方法?

Or is it other safe ways to let users (anyone) demo a PHP class?

推荐答案

是.您可以在php中使用eval语句(之前由John http://us2链接.php.net/manual/en/function.eval.php )，但是请务必小心.您真的不希望用户能够在您的计算机上自由运行代码.

Yes. You can use the eval statement in php (linked earlier by John http://us2.php.net/manual/en/function.eval.php), however be very careful. You really don't want users to be able to run code on your machine freely.

我的建议是尝试提出一种不同的演示方法-也许是一些灵活的示例...但是不要让他们直接运行代码

My recommendation would try to come up with a different approach to do demos - perhaps a flexible few examples... but don't let them run code directly
