icant想出如何从我的数组中编码一个有效的json 尝试了每一种可能的方式来编码json我没有运气谢谢你的时间

<?php
// this array is very large i used small piece as example
$listarray = array(
array(87,108,173,0,0),

//和jsonout.json的内容无效
//需要的输出就像这样 // json blew是用app制作并经过验证的

$listarray = array(
  array(87,108,173,0,0),
  array(87,108,173,0,1),
  array(87,108,173,0,2),
  array(87,108,173,0,3),
  array(133,157,215,1,47),
array(133,157,215,1,48),
array(133,157,215,1,49),
array(133,157,215,1,50),
array(133,157,215,1,51),
array(133,157,215,1,52),
);

$resultArray = array();
foreach ($listarray as $row) {
  $ind = $row[3] + 1;
  $name = $row[0] . '_' . $row[1] . '_' . $row[2];
  $val = $row[4] + 1;

  if (!isset($resultArray[$ind])) {
    $resultArray[$ind] = array();
  }

  if (!isset($resultArray[$ind][$name])) {
    $resultArray[$ind][$name] = array();
  }

  $resultArray[$ind][$name][] = $val;
}

echo json_encode($resultArray, JSON_PRETTY_PRINT);
