php搜索后添加内容 [英] php search and add content after

问题描述

在我的内容中，我有一个短代码"来显示具有不同参数的视频，具体取决于我希望视频的外观.例如:高度、宽度、视频等.

In my content I have a 'shortcode' to display videos with different parameters depending on how I want the video to look. For example: height, width, video, etc.

我可以在php中写什么来搜索[video {paramaters}]并在其后添加内容?

What can I write in php to search for [video {paramaters}] and add content after it?

记住 {parameters} 总是不同的.

推荐答案

好吧，当我需要做这样的事情时，我使用 preg_replace 或 preg_replace_callback..

Well, when I need to do something like this i use preg_replace or preg_replace_callback..

function videofunction($input){

//do something here and then:
return $whatever;

}

$content =  preg_replace('%\[video(.*?)\]%e', 'videofunction("\\1")', $content);

然后你必须想出逻辑=)

You then have to come up with the logic though =)

只需阅读您的帖子更多...你想保持标签不变，并在它后面添加一些东西..你可以用 preg replace 来做到这一点......像这样:

Just read your post more... You want to leave the tag as is, and add something after it.. You could do this with preg replace.. like this:

function videofunction($input){

$input .= "whatever else";
return $input;
}

preg_replace('%\[video.*?\]%e', 'videofunction("\\0")', $content);

虽然可能不是最好的方法，也许某种偏移捕获会更好?

Probably not the best way to do it though, maybe some kind of offset capture would be better?
