That probably means you’ll be encoding instances of domain-layer classes, such as BlogPost. Bringing JSON to Your Application’s Domain LayerĬomplex web backends are most likely to use PHP’s JSON features within the context of emitting HTTP responses. Values true, false and null are returned as TRUE, FALSE and NULL respectively.NULL is returned if the json cannot be decoded or if the encoded data is deeper than the recursion limit. The remainder are mostly specific options to customise the encoding used in particular scenarios. Returns the value encoded in json in appropriate PHP type.

You can obtain the full list of flags within the PHP documentation. PHP will try to substitute invalid values in order to produce some output, even if it’s not complete.

When the array is empty ( ), a JSON array would be created when it’s not empty ( ), an object would be emitted instead. This handles the case where a variable contains an associative array which might be empty. JSON_FORCE_OBJECT – Convert PHP numerical arrays to JSON objects instead of arrays.Many more flags are supported when encoding data. Take care around the order though – in a quirk of the PHP standard library, the position of these two optional parameters is switched compared to json_decode(). Like its decoding counterpart, json_encode() accepts $flags and $depth parameters. PHP scalar types map directly into JSON with no transformation. PHP objects and associative arrays will become JSON objects containing all the enumerable property/key-value pairs of the input value.

Data types are automatically handled to ensure they have an appropriate mapping in the generated JSON. PHP accepts any value as $value, except for resources.
