如何为关系传递序列化程序

Question

$input="(name eq \"xxxx\" and user:(post.id eq 6 and post.post eq \"testing\") and data eq \"Hello World!\")";

$inarr = [":(", ")","("];
$reparr   = [" and ", "", ""];
$input=str_replace($inarr, $reparr, $input);

$resultarr = explode(" and ", $input);

echo '[
      [
$resultarr[0]' . ',' .
      '"' . $resultarr[1] . '" => [' . 
   $resultarr[2] . ',' . 
   $resultarr[3] . ',' .
'],
   "' . $resultarr[4] . '",
 ],
 [
   "name",
   "user" => [
        post.id,
        post.post
   ],
   "data",
 ],
]';
