我正在尝试构建一个过滤器功能，以使编辑器用户可以轻松编写 html。

用户将输入如下文本：

Fusce eget sapien a tortor hendrerit pharetra sed a libero. Vestibulum quis dui sed elit         semper semper non molestie nulla. Curabitur suscipit feugiat varius.

{{accordion}}
  {{title}}1 This is the first accordion title{{title_end}}
  {{body}}1 This is the first accordion body{{body_end}}
  {{title}}1 This is the second accordion title{{title_end}}
  {{body}}1 This is the second accordion body{{body_end}}
  {{title}}1 This is the third accordion title{{title_end}}
  {{body}}1 This is the third accordion body{{body_end}}
{{accordion_end}}

Nulla consequat cursus turpis vitae pretium. Suspendisse iaculis nisl rhoncus justo luctus vel scelerisque diam volutpat.

{{accordion}}
  {{title}}2 This is the first accordion title{{title_end}}
  {{body}}2 This is the first accordion body{{body_end}}
  {{title}}2 This is the second accordion title{{title_end}}
  {{body}}2 This is the second accordion body{{body_end}}
  {{title}}2 This is the third accordion title{{title_end}}
  {{body}}2 This is the third accordion body{{body_end}}
{{accordion_end}}

Ut imperdiet odio quis diam ornare in congue purus rhoncus. Quisque scelerisque est sed sapien facilisis a facilisis turpis adipiscing. In hac habitasse platea dictumst.

请注意，手风琴块出现在其他文本之间，并且它们多次出现。

我正在使用模板对手风琴进行主题化，因此我希望手风琴结构为数组，然后将主题手风琴注入文本中的正确位置。

Array
(
    [0] => Array
        (
            [title] => 1 This is the first accordion title
            [body] => 1 This is the first accordion body
        )

    [1] => Array
        (
            [title] => 1 This is the second accordion title
            [body] => 1 This is the second accordion body
        )

    [2] => Array
        (
            [title] => 1 This is the third accordion title
            [body] => 1 This is the third accordion body
        )

)

我一直在搞乱 preg_replace_callback，但我真的找不到正确的方法来做到这一点。

到目前为止，我一直在这样做：

function format_accordion($text) {

  $regex = '#{{accordion}}(.+?){{accordion_end}}#is';

  return preg_replace_callback(
    $regex,
    "lolfunction",
    $text);
}


function lolfunction($accordion_content) {

  $title_regex = '#{{title}}(.+?){{title_end}}#is';
  $body_regex = '#{{body}}(.+?){{body_end}}#is';

  $data = array();

  foreach ($accordion_content as $key => $value) {
    $data[$key]['title'] = $key . " title"; // I need to find the titles
    $data[$key]['body'] = $key . " body"; // I need to find the bodies
  }



  return theme("kunsten_accordion", array("data" => $data));

}

theme() 函数将数组传递给 html 模板。我将函数命名为 lolfunction()，因为我曾希望将所有内容都放在一个函数 format_accordion() 中 :)

好的，我最终这样做了：

function format_accordion($text) {

  $regex = '#{{accordion}}(.+?){{accordion_end}}#is';

  return preg_replace_callback(
    $regex,
    function($content) {

      $title_regex = '#{{title}}(.+?){{title_end}}#is';
      $body_regex = '#{{body}}(.+?){{body_end}}#is';

      // find all titles
      preg_match_all($title_regex, $content[1], $titles);

      // find all bodies
      preg_match_all($body_regex, $content[1], $bodies);


      $data = array();

      foreach($titles[1] as $key => $title) {
        $data[$key]['title'] = $title;
      }
      foreach($bodies[1] as $key => $body) {
        $data[$key]['body'] = $body;
      }

      return theme("kunsten_accordion", array("data" => $data));
    },
    $text);
}
