php – Get class identify of present publish (CPT UI)

I used CPT UI to create customized publish varieties “Job Provides” which has a taxonomy with slug “job_offers_categories”.

Within the CPT Classes I’ve 4 classes:

1. Alternate Programme
2. Job Provide
3. Job Request (Newbie)
4. Job Request (Skilled)

What I need to obtain is to retrieve present publish class identify or slug so I can assign completely different image in response to the class. So in my WP_Query I can retrieve present publish, however tried a number of methods to realize what I would like, however will not be working. Is both giving me Array, undefined or nothing in any respect like the instance beneath.

Right here is my code (instance of present publish: “Job Provide”):

$post_query = new WP_Query(array(
    'writer'    =>  get_current_user_id(),
    'post_type' => 'job-offers'
));

whereas($post_query->have_posts()) {
    $post_query->the_post();//GET POST OBJECT
    $i = $post_query->current_post;//GET LOOP INDEX
    $post_id = get_the_id();//GET POST ID
    $view_post_URL = get_the_permalink();//URL FOR VIEW POST
    
    $phrases = get_the_terms( $post_id, 'job_offer_categories' );
    if ($phrases) {
        foreach($phrases as $time period) {
            echo $term->identify; 
            //Anticipated Consequence: "Job Provide" or "job-offer", choose to retrieve slug identify of customized class
        } 
    }
}

Additionally tried the next which:

$the_cat = get_the_category( $i->ID );
echo $the_cat; // is returning `Array`
foreach($the_cat as $cat) {
    echo $cat->identify; //Array to string conversion error
}
