尝试这个 ：

PHP 5.4 提供了 JSON_PRETTY_PRINT 选项以用于 json_encode() 调用。

http://php.net/manual/en/function.json-encode.php

$json_string = json_encode($data, JSON_PRETTY_PRINT);

或者

 $string = '{"a":"apple","b":"banana","c":"catnip"}';
 $pattern = array(',"', '{', '}');
 $replacement = array(",\n\t\"", "{\n\t", "\n}");
 echo str_replace($pattern, $replacement, $string);
