Get array of items from phpAdmin Wordpress - php

Question

In my phpAdmin I have a list of arrays that I need to be able to access in php Wordpress.
I need to get these two arrays and the variables associated with them but I can't find anywhere how to access this type of information.
Essentially I would like to loop through all these items and match one of their variables with the ID of specific posts - I have the post part.
wp_learnpress_sections
wp_learnpress_section_items
Basically the item_type is an lp_lesson which is a custom post type. I am able to grab all the posts from wp_posts so I figured I would be able to grab these other arrays?
Edit:
My theme function. This works for all the posts. However, I want to be able to find out which section_id a post belongs to.
add_action( 'wp_enqueue_scripts', 'win_9388244_format_lp_lesson' );
function win_9388244_format_lp_lesson() {
//Get post type of lp_lesson
$args = array(
'post_type' => 'lp_lesson',
'numberposts' => 99999
);
$posts = get_posts($args);
foreach($posts as $post) {
update_post_meta( $post->ID, 'wpk_icon_text', 'Test' );
}
}

Full function that does it:
function win_9388244_format_lp_lesson() {
//Get post type of lp_lesson
$args = array(
'post_type' => 'lp_lesson',
'numberposts' => 99999
);
$posts = get_posts($args);
global $wpdb;
$sections = $wpdb->get_results( "SELECT section_item_id, section_id, item_id FROM wp_learnpress_section_items", ARRAY_A );
$items = $wpdb->get_results( "SELECT section_course_id, section_id FROM wp_learnpress_sections", ARRAY_A );
foreach($posts as $post) {
$lesson_id = $post->ID;
foreach($sections as $section) {
if($section['item_id'] == $lesson_id) {
$currentSection = $section['section_id'];
foreach($items as $item) {
if ($item['section_id'] == $currentSection) {
$course = $item['section_course_id'];
//switch $course with predefined variables for courses
}
}
}
}
}
}
