获取标签之间的所有字符串并回显它们？ [复制]

Question

可能重复：
Get content between two strings PHP

好的，这是我的定义：

这是我的 $content 示例：

<!--nextpage-->First Title Here<!--nexttitle-->

some more text here

and here and here and here

a little more here!

<!--nextpage-->Second Title Here<!--nexttitle-->

some more text here

and here and here and here

a little more here!

<!--nextpage-->Third Title Here<!--nexttitle-->

some more text here

and here and here and here

a little more here!

我如何运行一个函数来查找所有“get_all_strings_between()”并将它们回显到 $content 的顶部：

**First Title Here** / **Second Title Here** / **Third Title Here**

and then my content HERE!

谢谢！！

如果我正确理解了你的问题，这个正则表达式会做到：

function get_all_strings_between($content) {
    preg_match_all('/<!--nextpage-->([^<]*)<!--nexttitle-->/', $content, $m);

    return implode(' / ', $m[1]);
}

// then you echo get_all_strings_between($content) where you need it

如果我不正确，请提供更多信息这些nextpage 和nexttitle 标签是什么？字面意思是这样的吗？
