PHP "Pretty Print" JSON_Encode

Pretty-Printing JSON with PHP

PHP 5.4 offers the JSON_PRETTY_PRINT option for use with the json_encode() call.

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

<?php
...
$json_string = json_encode($data, JSON_PRETTY_PRINT);

PHP pretty print json_encode

PHP has JSON_PRETTY_PRINT option since 5.4.0 (release date 01-Mar-2012).

This should do the job:

$json = json_decode($string);
echo json_encode($json, JSON_PRETTY_PRINT);

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

Note: Don't forget to echo "<pre>" before and "</pre>" after, if you're printing it in HTML to preserve formatting ;)

Json encode PRETTY PRINT printing out with slashes in php

The data you get from wp_remote_get is already a perfectly encoded JSON string, no need to encode again.

When you encode again, PHP generates a structure with one element, the string you originally get, and escapes all the quotes to form valid JSON.

So you can output the data directly :

$response = wp_remote_get( 'URL TO JSON DATA' ));
header('Content-Type: application/json');
echo $response;

Why the code is not printing in Pretty Json format?

You just need to add a second a parameter to json_encode() and add <pre> tag. Like this:

echo '<pre>';
echo json_encode($data, JSON_PRETTY_PRINT);
echo '</pre>';

JSON pretty print without use json_decode in php

Only a parser can understand the JSON, so you can either do what you proposed or write your own parser. If you have access to the origin of the JSON, make it pretty in the first place.

How to pretty print JSON with wp_json_encode()?

You can make use of wp_json_encode() options parameter.

Setting options to JSON_PRETTY_PRINT as an argument will make the function use whitespace in returned data to format it:

wp_json_encode($data, JSON_PRETTY_PRINT);

How to do jscon encode :: pretty print and unescaped slashes at same time in php

json_encode takes options as a bit mask. You can use multiple with the | character. So try:

$v = json_encode($arr, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES);

Pretty print JSON that's already encoded in PHP

json_encode($json, JSON_PRETTY_PRINT); 

Save it like that then display it with <pre> and <code>(if needed) tags wrapped around it..
