Would like to Edit some Core plugin PHP

Hi i made an edit @ some core plugin php file such as
listing-listview.php
Example
<?php
/**
* Called before the post excerpt on the listings view template.
*
* @since 1.0.0
* @param object $post The post object.
* @see ‘geodir_after_listing_post_excerpt’
*/
do_action(‘geodir_before_listing_post_excerpt’, $post); ?>
<?php echo geodir_show_listing_info(‘listing’); ?>

I start make comment from this

<!– <div class=”geodir-entry-content”>

<?php
/**
* Filter to hide the listing excerpt
*
* @since 1.5.3
* @param bool $display Display the excerpt or not. Default true.
* @param string $view The view type, default ‘listview’.
* @param object $post The post object.
*/
$show_listing_excerpt = apply_filters(‘geodir_show_listing_post_excerpt’, true, ‘listview’, $post);
if ($show_listing_excerpt) {
if ( isset( $character_count ) && ( $character_count || $character_count == ‘0’ ) ) {
$content_out = geodir_max_excerpt( $character_count );
} else {
$content_out = get_the_excerpt();
}
if ( ! empty( $content_out ) ) {
echo “<p>” . $content_out . “</p>”;
}
}
?></div> –> my End comment

INTO these :

<div class=”geodir-entry-content”> <?php $check_button= $post->geodir_Button_enable; if($check_button){ echo “<span class=’glf-button’ data-glf-cuid=”,$post->geodir_CUID,” data-glf-ruid=”,$post->geodir_RUID,” data-glf-auto-open=’false’>ORDER NOW</span><script src=’https://www.foodbooking.com/widget/js/ewm2.js’ defer async ></script>”; } ?></div>

by edit core php file directly it make me can’t update my geodirectory plugin

Would you please suggest me another to edit php file but not in core file directly ?
