修改链接目标

On a given search result page I need to modify the link targets on specific results, like:

• Every http://www.name.com/company/company to http://www.name.com/company/;
• Every http://www.name.com/company/something to http://www.name.com/company/#something;
• Every http://www.name.com/business/business to http://www.name.com/business/;
• Every http://www.name.com/business/somethingelse to http://www.name.com/business/#somethingelse;
• Every http://www.name.com/portfolio/projectname to http://www.name.com/portfolio/;

Please notice that this is a multilanguage website and URLs might also come in the form of http://www.name.com/en/company/something-en, where I will need to change it to http://www.name.com/en/company/#something, and so on.

I believe this might be achieved using regular expressions with PHP but I am not skilled enough to write something solid from scratch.

Pratical example, change the following links inside the search-content div (links generated by the wordpress loop):

    <div id="search-content">

        <h3><?php _e( 'Search Results for', 'foundationpress' ); ?> <span>"<?php echo get_search_query(); ?>"</span>:</h3>

        <?php if ( have_posts() ) : ?>

            <?php while ( have_posts() ) : the_post(); ?>
                <div id="post-<?php the_ID(); ?>" <?php post_class('blogpost-entry'); ?>>
                    <header>
                        <h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
                    </header>
                    <div class="entry-content">
                        <?php the_excerpt(); ?>
                    </div>
                </div>
            <?php endwhile; ?>

            <?php else : ?>
                <?php get_template_part( 'template-parts/content', 'none' ); ?>

        <?php endif;?>

    </div>

Tbis is the function:

function processHref($input_url) {
    $regex_one  = '#http://([^/]+)/([^/]+)/([^/]+)#';
    $regex_two  = '#http://([^/]+)/([a-z]{2})/(.+)/([^-]+)#';

    if(preg_match($regex_one, $input_url, $matches)) {
        $domain = $matches[1];
        $first  = $matches[2];
        $second = $matches[3]; 
    }
    elseif(preg_match($regex_two, $input_url, $matches)) {
        $domain = $matches[1];
        $lang   = $matches[2];
        $first  = $matches[3];
        $second = $matches[4];
    }

    $output_url = "http://$domain/";

    if(isset($lang))  $output_url .= "$lang/";
    if(isset($first)) $output_url .= "$first/";
    if($first != $second && $first != "portfolio")
        $output_url .= "#$second";

    return $output_url;
}    
?>
