JSON indentation in PHP

This question already has an answer here:

Pretty-Printing JSON with PHP 20 answers

From PHP 5.4 onwards, json_encode has a JSON_PRETTY_PRINT flag

$pretty=json_encode($foo, JSON_PRETTY_PRINT);

If you're stuck with an ancient version of PHP, then the manual page for json_encode includes a user-contributed sample showing how to pretty-print JSON.

In fact, json_encode has an option to do pretty-print in PHP 5.4 . To use it:

<pre>
<?php echo nl2br(json_encode($yourArrayOrObject, JSON_PRETTY_PRINT)); ?>
</pre>
