WOOF :: json_get( String $url, Boolean $assoc = false, String $cache = false, Object $req = null )
The JSON object if the request is successful and the assoc argument is false.
An associative array representing the JSON output if the request is successful and assoc is true.
An array of objects or associative arrays, if the json output has an array at the root level.
false if the JSON could not be retrieved.
Retrieves a json object or associative array by requesting a JSON string from a remote URL and decoding it. This method can also cache the result of the request using the WordPress transients API, accepting the same duration string accepted by the WOOF::cache.
The URL to retrieve JSON from.
Boolean $assoc = false
Whether to convert the JSON string to an assocative array (true) or an object (false).
String $cache = false
For setting a value only. Either an:
* integer number of seconds to store the transient
* a string describing the time period, as parsed by the WOOF::seconds function (see related methods).
* OR false if you do not wish to cache the request. This may be appropriate if the JSON API already caches its output.
An output parameter, allowing you to capture the request object created by the wp_remote_get method (which is used to request the JSON string). This will only be populated if a request is required, and may be useful for debugging purposes to discover errors.
