• Pretty-Printing JSON with PHP 22 answers

i was just echoing my statement results as JSON-Object. But the function json_encode() puts out everything into a single line like that:

{"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3}

Now imagine a JSONobject with hundred of more entries.

Is there a way to add some <br> tags or tab stops to improve the readabilty? this should only be for test purposes not for further parsing.

Checkout the JSON_PRETTY_PRINT flag.

echo json_encode([[[[[[['a'=>'b']]]]]]],JSON_PRETTY_PRINT);

Outputs :

[
    [
        [
            [
                [
                    [
                        {
                            "a": "b"
                        }
                    ]
                ]
            ]
        ]
    ]
]
