    There will be times when you need to merge separate data sets into a new single set.

    This code demonstrates how to merge the XOR dataset from two separate files into a single training file.

    File (xor_part_1.data):
    1 2 1
    -1 -1
    -1

    File (xor_part_2.data):
    3 2 1
    -1 1
    1
    1 -1
    1
    1 1
    -1

    Resulting File (xor_complete.data):
    4 2 1
    -1 -1
    -1
    -1 1
    1
    1 -1
    1
    1 1
    -1

    <?php
    // Create partial data resources
    $train_data_1 = fann_read_train_from_file("xor_part_1.data");
    $train_data_2 = fann_read_train_from_file("xor_part_2.data");

    // Merge into new data resource
    $train_data = fann_merge_train_data ($train_data_1, $train_data_2);

    // Remove the partial data resources from memory
    fann_destroy_train ( $train_data_1 );
    fann_destroy_train ( $train_data_2 );

    // Save the new complete Data file
    fann_save_train ( $train_data , "xor_complete.data");

    // Remove the complete data resources from memory
    fann_destroy_train ( $train_data );

    echo     'All Done!' . PHP_EOL;
    ?>
