/**
* Formats a JSON string for pretty printing
*
* @param string $json The JSON to make pretty
* @param bool $html Insert nonbreaking spaces and
s for tabs and linebreaks * @return string The prettified output */ $arr = array("ret"=>0,"data"=>array('a' => 1,'b' => "编程之家",'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 = "@H_301_3@"; } 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": { "a": 1,"b": "\u811a\u672c\u4e4b\u5bb6","c": 3,"d": 4,"e": 5 } } **/ ?>
