How to make JSON readable?

Question

PHP

There is a json file. It is updated from time to time by means of php. But also this file is often edited manually. But here's the trouble, after encoding to json through php, it becomes one line.
Is there a php class that turns this string into a human readable form?
For example
{
"foo":["bar","baz"],
"key":true
}
