我的循环显示了一个值列表，在它们下面是该值的帖子标题和图像。

问题是，由于某些值与多个帖子关联，因此会显示多个图像。我只需要一张图片。有没有办法只显示我的foreach 环

这是我的代码：

<?php 
$the_query = new WP_Query(array(
    \'post_type\'     => \'post\',
    \'post_status\'   => \'publish\',
    \'meta_key\'      => \'colors\',
));

$results = [];
while ( $the_query->have_posts() ) {

    $the_query->the_post(); 
    $credits = get_field(\'colors\');

    if( !empty($color) ) {

        foreach( $colors as $color ) {  
           $results [$color][]=array(
               \'title\' => get_the_title(),
               \'img\' => get_field(\'photo\')
           );
       }
    }
}

foreach ($results as $color => $posts) {

   foreach($posts as $post) {  /* This shows multiple images but I only need one */
        echo \'<img src="\'.$post[\'img\'][\'url\'].\'">\';
    }


   echo \'<div><h2>\'.$color.\'</h2>\';

    foreach($posts as $post) {
        echo \'<div>\'.$post[\'title\'].\'</div>\';
    }

   echo \'</div>\';
}

wp_reset_postdata();?>
