Dynamically create array from page title

Question

I have a simple page structure like Page One, Page Two, Page Three.

Each page has tag of 'content'.

In the Wordpress loop how could I create an array for each page with the page title as the array name.

My code is like this.

    <?php
        $mt_test_args = array(
            'post_type' => 'page',
            'tag' => 'content',
            'order' => 'ASC'
        );

        $mt_test_loop = new WP_Query($mt_test_args);

        if($mt_test_loop->have_posts()):
            while($mt_test_loop->have_posts()):
                $mt_test_loop->the_post();

                //Trying to create array here from page title.

            $arr_name = get_the_title();

                $arr_name = str_replace(' ','_',$arr_name);

                $arr_name = array();

    ?>  

    <option><?php the_title(); ?></option>

    <?php endwhile; endif; ?>

    <?php wp_reset_postdata(); ?>

This is demo code, the actual set up is a lot more complex

Answer 1

I think this is what you're looking for:

$$arr_name = array();

If $arr_name = 'post_title', then the above would mean:

$post_title = array();
