我需要逃避吗？(Do I need to escape this?)

我需要逃避吗？(Do I need to escape this?)

这可能有点不寻常，但我需要echo <?php 。 不过，我认为PHP将它视为一个实际的<?php并开始执行代码，而不是将其视为字符串。 我如何逃避<?php和?>以便将它们视为字符串？ 手册中没有关于此的内容。

谢谢，我知道这有点不寻常。

It might be a bit unusual, but I need to echo <?php. However, I think that PHP treats it as an actual <?php and starts executing code instead of treating it as a string. How can I escape <?php and ?> so they can be treated as strings? There was nothing in the manual about this.

Thanks, I know this is a bit unusual.

您可以使用&lt; 和&gt; html实体（替换'<'和'>'）。 这些只能在浏览器中处理，所以PHP不会尝试运行该代码。

You can use the &lt; and &gt; html entities (to replace '<' and '>'). These are only handled in the browser, so PHP would not attempt to run that code.
