Access a certain property in a large PHP object

Question

I ran a PHP query for my WordPress site with the following code:

$args = array(
    'post_type' => 'cases',
    'posts_per_page' => 3,
    offset => 2
);
$the_query1 = new WP_Query( $args );
if ( $the_query1 -> have_posts() ):
    print_r($the_query1);
while ( $the_query1->have_posts() ): $the_query1->the_post();

This is the object returned:

WP_Query Object

            [post_type] => cases

If you look in the middle of the object, there is an object property called [posts] which is an array consisting of three properties. I would like to access this property and then check if the second index ([1]) is true and do something based on that. Unfortunately, I am not sure how to access that property in PHP. Please advise.

Answer 1

After dumping the object using print_r(), I was able to access the posts array using:

print_r($the_query1 -> posts);
