The examples in this article describe how PHP custom functions format JSON data. Share to everyone for your reference, specific as follows:

<?php/** * Formats A JSON string for pretty printing * * @param string $json The JSON-make pretty * @param bool $html Insert nonbreaking spaces and <br/>s for tabs and linebreaks * @return string The prettified o Utput */$arr = array ("ret" =>0, "Data" =>array (' a ' => 1, ' B ' => "cloud-Habitat community", ' C ' => 3, ' d ' => 4, ' E ' => 5
));
$json = Json_encode ($arr);
    function _format_json ($json, $html = False) {$tabcount = 0;
    $result = ';
    $inquote = false;
    $ignorenext = false;
      if ($html) {$tab = "   ";
    $newline = "<br/>";
      else {$tab = "\ t";
    $newline = "\ n";
      for ($i = 0; $i < strlen ($json); $i + +) {$char = $json [$i];
        if ($ignorenext) {$result. = $char;
      $ignorenext = false;
            else {switch ($char) {case ' {': $tabcount + +; $result. = $char. $newline.
            Str_repeat ($tab, $tabcount);
  Break        Case '} ': $tabcount-; $result = Trim ($result). $newline. Str_repeat ($tab, $tabcount).
            $char;
          Break Case ', ': $result. = $char. $newline.
            Str_repeat ($tab, $tabcount);
          Break

            $result. = $char;
          Break

            $result. = $char;
          Break
        Default: $result. = $char;
  }} return $result;
echo _format_json ($json); 
/* {"ret": 0, "data": {"a": 1, "B": "\u811a\u672c\u4e4b\u5bb6", "C": 3, "D": 4, "E": 5}} **/
