WooCommerce - getting the correct data value for the selection field after sending

Question

I use Woocommerce and I created a selection window in the admin panel. I fill in the information in the selection box through a flat file. Everything is working fine (almost).

The part that I'm stuck on, after choosing the "choice" I want and save. I get an array , not the actual one . I'm close, but I just can't put it on her. $key $value

Update: here is my full code:

function woo_add_custom_admin_product_tab() {
?>
    <li class="custom_tab"><a href="#custom_tab_data"><?php _e('Additional Information', 'woocommerce'); ?></a></li>
<?php
}
add_action( 'woocommerce_product_write_panel_tabs', 'woo_add_custom_admin_product_tab' );


function woo_add_custom_admin_fields() {    
    global $woocommerce, $post;

    echo '<div id="custom_tab_data" class="panel woocommerce_options_panel">';
    echo '<div class="options_group">';

    // Select - Breed1
    if (file_exists ( plugin_dir_path(__FILE__) .'breed.txt')) {
        $breedData = file_get_contents ( plugin_dir_path(__FILE__) .'breed.txt');
        $breedArray = explode ("\n", $breedData);
    }

    woocommerce_wp_select(array(
        'id'      => '_select_breed1',
        'label'   => __( 'Select Primary Breed', 'woocommerce' ),
        'desc_tip'    => 'true',
        'description' => __( 'Select the primary breed of the pet.', 'woocommerce' ),
        'options' => $breedArray
    ) );
    echo '</div>';
    echo '</div>';
}
add_action( 'woocommerce_product_write_panels', 'woo_add_custom_admin_fields' );


// Save Fields;
function woo_add_custom_general_fields_save( $post_id ){
    // Text Field - Pet Name
    $woocommerce_text_field = $_POST['_pet_name'];
    if( !empty( $woocommerce_text_field ) )
       update_post_meta( $post_id, '_pet_name', esc_attr( $woocommerce_text_field ) );

    // Select Field - Breed
    $woocommerce_select = $_POST['_select_breed1'];
    if( !empty( $woocommerce_select ) )
        update_post_meta( $post_id, '_select_breed1', esc_attr( $woocommerce_select ) );
}
add_action( 'woocommerce_process_product_meta', 'woo_add_custom_general_fields_save' );

My breed.txt file contains 3 lines (elements):

Please Select a breed...
Abyssinian
Affenpinscher

And the generated array looks like this:

Array ( 
    [0] => Please Select a breed... 
    [1] => Abyssinian 
    [2] => Affenpinscher 
)

So when I select , I get the value instead . "Affenpinscher" "2" "Affenpinscher"

What am I doing wrong? How can I solve this problem?

thank

//Create the fields
function woo_add_custom_admin_fields() {

    echo '<div id="custom_tab_data" class="panel woocommerce_options_panel">';
    echo '<div class="options_group">';

    if (file_exists ( plugin_dir_path(__FILE__) .'breed.txt')) {

        $breedArray = explode ("\n", $breedData);

        //Storing the array in wp_options table

    woocommerce_wp_select( array(

// Save Created Fields;

    // Saving the corresponding value (from "$wc_select" selected key) to database

    }
}
add_action( 'woocommerce_process_product_meta', 'woo_add_custom_general_fields_save' );

wp_postmeta (post_id), 2 meta_keys:
- '_select_breed_key1',
- '_select_breed_value1',

, ( ):

<?php

// Third parameter is set to "true" as it is a string (Not an array) 
$breed_value1 = get_post_meta( $post_id, '_select_breed_value1', true );
echo $breed_value1;
