title: Indentation size with JSON_PRETTY_PRINT
body: <p>The php function <a href="http://php.net/manual/en/function.json-encode.php" rel="noreferrer">json_encode()</a> has an option to set indentation in the outputted json for a "pretty" version. This option is called:  JSON_PRETTY_PRINT</p>
  
  <p>A minor pet peeve is that this feature uses 4 spaces in said indentation. </p>
  
  <p>Is there is a way to make it use 2 spaces instead of 4 or an efficient way to process the output to reduce the 4 spaces to 2 - without it breaking any of the json keys/values which may have spaces in them. </p>
