查找匹配和填充數組

Question

我試圖建立一個過濾器函數，使編輯器用戶可以輕鬆地編寫html。

的用戶要輸入文字是這樣的：

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. 

注意，手風琴塊文本的其他部分之間出現，且都出現在多次出現。

我正在使用模板來主題手風琴，所以我希望手風琴結構化爲數組，然後將主題手風琴注入文本中的正確位置。

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preg_replace_callback，但我真的找不到正確的方式來做到這一點。

到目前爲止，我一直都在做這樣的：

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)); 

} 

主題（）函數傳遞數組到HTML模板。我命名的函數lolfunction（），因爲我曾希望在短短的一個功能format_accordion（）:)一切
