Perform an HTTP request; does not wait for reply & you will never get it back.
Parameters
$url: A string containing a fully qualified URI.
array $options: (optional) An array that can have one or more of the following elements:
- headers: An array containing request headers to send as name/value pairs.
- method: A string containing the request method. Defaults to 'GET'.
- data: A string containing the request body, formatted as 'param=value¶m=value&...'. Defaults to NULL.
- max_redirects: An integer representing how many times a redirect may be followed. Defaults to 3.
- timeout: A float representing the maximum number of seconds the function call may take. The default is 30 seconds. If a timeout occurs, the error code is set to the HTTP_REQUEST_TIMEOUT constant.
- context: A context resource created with stream_context_create().
Return value
bool return value from advagg_async_send_http_request().
