您可以使用get_variation_prices( $for_display = false ) 方法或get_variation_regular_price( $min_or_max = \'min\', $for_display = false )

类似这样：

global $product;
var_dump( $product->get_variation_prices() );

https://github.com/woocommerce/woocommerce/blob/master/includes/class-wc-product-variable.php#L97

/**
 * Get the min or max variation regular price.
 *
 * @param  string  $min_or_max Min or max price.
 * @param  boolean $for_display If true, prices will be adapted for display based on the `woocommerce_tax_display_shop` setting (including or excluding taxes).
 * @return string
 */
public function get_variation_regular_price( $min_or_max = \'min\', $for_display = false ) {
    $prices = $this->get_variation_prices( $for_display );
    $price  = \'min\' === $min_or_max ? current( $prices[\'regular_price\'] ) : end( $prices[\'regular_price\'] );
    return apply_filters( \'woocommerce_get_variation_regular_price\', $price, $this, $min_or_max, $for_display );
}

https://github.com/woocommerce/woocommerce/blob/master/includes/class-wc-product-variable.php#L80

/**
