This is because the current indent is stored in a variable JSON_G(encoder_depth), which is shared between json_encode() calls.

Test script:

class Foo implements JsonSerializable {
    public function jsonSerialize() {
        return json_encode([1], JSON_PRETTY_PRINT);

echo json_encode([new Foo]), "\n";

Expected result:
["[\n    1\n]"]

Actual result:
["[\n        1\n    ]"]

I'm hitting this in production at my workplace; specifically, when json_encode causes the interpereter to run out of memory and abort requests in mod_php, php_json_encode_array doesn't have a chance to decrement the encoder_depth variable, leaving a thread-local inconsistency in the interpereter.

The bug is caused by the fact that globals are used for encoder depth. I plan to introduce a separate context for each encoder run which will fix this and couple of others bugs related to globals in json encoding. This won't happen before 7.1
