What is JSON?
PHP JSON Decode Function
In PHP, the json_decode() function is used to decode a JSON string into a PHP object. The result object can be any PHP data type, except for resource pointers such as a database or file descriptor. Following is the syntax of the json_decode() function:
- string: specifies the value to be decoded. It only works with UTF-8 encoded strings.
- assoc (Optional): specifies a boolean value If set to "true", the returned object will be converted to an associative array. If set to "false", it returns an object. The default value is "false".
- depth (Optional): specifies the recursion depth. The default JSON decoding recursion depth is 512.
- options (Optional): specifies a bitmask that determines how JSON objects will be converted to PHP objects. The decode function supports the following bitmasks: JSON_BIGINT_AS_STRING, JSON_INVALID_UTF8_IGNORE, JSON_INVALID_UTF8_SUBSTITUTE, JSON_OBJECT_AS_ARRAY, JSON_THROW_ON_ERROR. You can learn more about JSON decodeding bitmasks in the PHP documentation.
