没有空格的php运算符

I have this shopkeeper running in Wordpress. And I want to change the colon to parentheses but it gets weird , I don't want spaces between it just like this " (€5,50).

I've been trying to fix this problem for almost a day.

really hope to see any answers.

here is the html : gyazo.com/f05c00f01d2522aa962d90f5c0fcc5ea

method function :

function wc_cart_totals_shipping_method_label( $method ) {
    $label = $method->label;

    if ( $method->cost > 0 ) {
        if ( WC()->cart->tax_display_cart == 'excl' ) {
            $label .= ': ' . wc_price( $method->cost );
            if ( $method->get_shipping_tax() > 0 && WC()->cart->prices_include_tax ) {
                $label .= ' <small class="tax_label">' . WC()->countries->ex_tax_or_vat() . '</small>';
            }
        } else {
            $label .= '(' . wc_price( $method->cost + $method->get_shipping_tax() ).')';
            if ( $method->get_shipping_tax() > 0 && ! WC()->cart->prices_include_tax ) {
                $label .= ' <small class="tax_label">' . WC()->countries->inc_tax_or_vat() . '</small>';
            }
        }
    } elseif ( $method->id !== 'free_shipping' ) {
        $label .= ' (' . __( 'Free', 'woocommerce' ) . ')';
    }

    return apply_filters( 'woocommerce_cart_shipping_method_full_label', $label, $method );
}

code where I print :

            <select name="shipping_method[<?php echo $index; ?>]" data-index="<?php echo $index; ?>" id="shipping_method_<?php echo $index; ?>" class="shipping_method">
                <?php foreach ( $available_methods as $method ) : ?>
                    <option value="<?php echo esc_attr( $method->id ); ?>" <?php selected( $method->id, $chosen_method ); ?>><?php echo wp_kses_post( wc_cart_totals_shipping_method_label( $method ) ); ?></option>
                <?php endforeach; ?>
            </select>

Before the result try to add this:

$label = '(€'.preg_replace("/\([\s]+?/", "", str_replace(array('€', ' '), '', $label));

First use str_replace to remove html entities, seconds use a regex to remove all whitespaces after the ( and finally append at the start of the string "(€"
