我厌倦了esc\\u url，但它不起作用。

if ( $power_by ) { ?>
            <div class="sponsor-credits">
                <span class="sponsor-credits__label">Powered by </span>
                <span class="sponsor-credits__sponsor">
                    <?php
                    if ( $sponsor_link ) {
                        printf(
                            \'<a href="%1$s" class="sponsor-credits__link" target="_blank" alt="%2$s">%3$s</a>\',
                            esc_url( $sponsor_link ),
                            esc_attr( $sponsor_name ),
                            $power_by
                        );

$power_by     = \'<img class="sponsor-credits__logo" src="\' . esc_url( $sponsor_logo[0] ) . \'">\';
