Access the same page from multiple urls (wildcard)

You can use template_include, but before you hook to this filter you must do the following steps:

  1. Create page template. e.g: page-target.php

    <?php
    /**
     * Template Name: Page Target
     */
    ...
    
  2. Manually query the contents of target-page on page-target.php template, because the global $post will be referencing to your some-prefix-* page.

  3. (Optional): Edit and apply page template Page Target to your /target-page from the Page Attributes

Then add the following to your functions.php file

add_filter('template_include', function($template) {
    global $post;

    $prefix = 'some-prefix-'; // Your prefix
    $prefixExist = strpos($post->post_name, $prefix) !== false;

    if ($prefixExist) {
        return locate_template('page-target.php'); //Your template
    }

    return $template;
});

Above filter will override the template with page-target.php if condition met, otherwise default

Edit:

I think I have found a better way to resolve this using add_rewrite_rule

function custom_rewrite_basic() {
  $page_id = 123; //Your serve page id
  add_rewrite_rule('^some-prefix-.*', 'index.php?page_id=' . $page_id, 'top');
}
add_action('init', 'custom_rewrite_basic');

IMPORTANT: Do not forget to flush and regenerate the rewrite rules database after modifying rules. From WordPress Administration Screens, Select Settings -> Permalinks and just click Save Changes without any changes.
