本文讲述了php格式化json函数的示例代码。分享给大家供大家参考,具体如下:

<&#63;php
$arr = array("ret"=>0,"data"=>array('a' => 1, 'b' => '2', 'c' => 3, 'd' => 4, 'e' => 5));
$json = json_encode($arr);
/**
* Formats a JSON string for pretty printing
*
* @param string $json The JSON to make pretty
* @param bool $html Insert nonbreaking spaces and <br />s for tabs and linebreaks
* @return string The prettified output
*/
function _format_json($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;
   case '"':
   $inquote = !$inquote;
   $result .= $char;
   break;
   case '\\':
   if ($inquote) $ignorenext = true;
   $result .= $char;
   break;
   default:
   $result .= $char;
  }
  }
 }
 return $result;
}
echo _format_json($json);
/*
{
 "ret": 0,
 "data": {
