If the JSON failed to be decoded or the JSON is deeper than given depth then null gets returned. When true, false, or null is passed for JSON, the function returns same true, false, or null respectively. Basic types Top-level Non-Object, Non-Array Values¶ The old version of JSON specified by the obsolete RFC 4627 required that the top-level value of a JSON text must be either a JSON object or array (Python dict or list), and could not be a JSON null, boolean, number, or string value Performance wise, simdjson-go runs on average at about 40 to.

It is not safe to rely only on the return value being NULL to detect errors.depth: Maximum nesting depth of the JSON to be decoded.When true is passed, JSON object will be converted into associative array when false is passed, JSON object will be returned as stdClass object when NULL is passed, it will return associative array or object depending on the JSON_OBJECT_AS_ARRAY flag. This function only works with UTF-8 encoded strings. json: The JSON string passed to be decoded to php variable.So, to check that the jsondecode() argument is a valid JSON, you can simply check that its return value is not NULL. By default, jsondecode() returns NULL if it cannot decode the provided JSON string.
Validate each variable contained inside the JSON object. Json_decode ( string $json, ? bool $associative = null, int $depth = 512, int $flags = 0 ) : mixed Make sure it is a valid JSON string, by checking decoding errors.
