PHP - 使用正则表达式模式删除短代码和内容

问题描述

我有以下字符串:

$text = My example text [shortcode_name]content of shortcode[/shortcode_name] is cool.

还有以下模式:

$pattern= '/\[(\/?shortcode_name.*?(?=\]))\]/';

它给了我以下结果:

preg_replace($pattern,'',$text);
My example text content of shortcode is cool.

这就像删除短代码的魅力.
我正在寻找的是删除短代码和其间的所有内容.
我要找的结果是:

This works like a charm to remove the shortcode.
What I'm looking for is to remove the shortcode and all content in between.
The result that I'm looking for is:

My example text is cool.

推荐答案

给你:

$pattern= '/\[(shortcode_name)\].*?\[\/\1\] ?/';

说明:

• 匹配 [
• 后跟shortcode_name"(在 (...) 中捕获，以便在后面的步骤中重用，见下文)
• 其次是]
• 跟随任何东西，非贪婪(重要！)
• 其次是 [/
• 接着是前面 (...) 中匹配的内容，在这个例子中是shortcode_name"
• 其次是]
• 后跟 1 个或零个空格

• match [
• followed by "shortcode_name" (captured within (...) for reuse in a later step, see below)
• followed by ]
• followed by anything, non-greedily (important!)
• followed by [/
• followed by what was matched in (...) earlier, in this example "shortcode_name"
• followed by ]
• followed by 1 or zero space
