(PECL fann >= 1.0.0)

fann_train — Train one iteration with a set of inputs, and a set of desired outputs

### Description

fann_train ( resource `$ann` , array `$input` , array `$desired_output` ) : bool

Train one iteration with a set of inputs, and a set of desired outputs. This training is always incremental training, since only one pattern is presented.

### Parameters

`ann`

  Neural network resource.

`input`

  An array of inputs. This array must be exactly fann_get_num_input() long.

`desired_output`

  An array of desired outputs. This array must be exactly fann_get_num_output() long.

### Return Values

Returns `TRUE` on success, or `FALSE` otherwise.
