字符串到数组的顺序与PHP相同

I have string list of data like so :

Category(1,2,"some text");
post(111,233,"post");
post(111,233,"post");
post(111,233,"post");
Category(1,2,"some text");
post(111,233,"post");
post(111,233,"post");
post(111,233,"post");
post(111,233,"post");
post(111,233,"post");

I need to convert this to array in same order, some thing like this for example :

Array
(
[0] => Array
   (
       ['category'] => Category(1,2,"some text")
       ['posts'] => Array
                (
                    [0] => post(111,233,"post")
                    [1] => post(111,233,"post")
                    [2] => post(111,233,"post")
                )
   )
[2] => Array
   (
       ['category'] => Category(1,2,"some text")
       ['posts'] => Array
                (
                    [0] => post(111,233,"post")
                    [1] => post(111,233,"post")
                    [2] => post(111,233,"post")
                    [3] => post(111,233,"post")
                    [4] => post(111,233,"post")
                )
   )
)

I could get the Categories array alone and posts array alone, but how can I put them together in one array in the same order ..

preg_match_all("/(category)\(+(.*?)\)/",$string,$cats , PREG_SET_ORDER);
preg_match_all("/(post)\(+(.*?)\)/",$string,$posts , PREG_SET_ORDER);

print_r($cats);
print_r($posts);

Thank you

You can tokenize the string and then parse each item one by one, like this:

$result = array();
$token_list = explode(";
",$string);
$category_counter = -1;//index trick for the first occorrence of Category

foreach($token_list as $token){
  if(substr($token,0,8) == "Category"){
    $category_counter++;
    $result[$category_counter]["category"] = $token;
  }else{
    $result[$category_counter]["posts"][] = $token;
  }
}
