Into this:
进入这个：
{it}CONTENT{/it}
While keeping CONTENT intact?
同时保持内容完整？
回答by Mave
preg_replace('/<span class="it">(.*?)<\/span>/', '{it}{/it}', $text)
This is not the most versatile solution, but this works for your code. There is the possibility to have the content of the class attribute as a variable as well, but that won't be too hard to figure out now.
这不是最通用的解决方案，但这适用于您的代码。也有可能将 class 属性的内容作为变量，但现在不难弄清楚。
