Wordpress get attachment image src using foreach

Question

Using wordpress get_post_meta $key. I was able to output attachment image in single.php using Function Reference/wp get attachment image src for single attachment id:

<?php 
$attachment_id = get_post_meta($post->ID, 'attachment-id', true); // attachment ID

$image_attributes = wp_get_attachment_image_src( $attachment_id ); // returns an array
if( $image_attributes ) {
?> 
<img src="<?php echo $image_attributes[0]; ?>" width="<?php echo $image_attributes[1]; ?>" height="<?php echo $image_attributes[2]; ?>">
<?php } ?>

Since I am coding image gallery, I intend to use php foreach function to html output multiple images html code replacing the single post_meta $key with multiple ids array like (55,32,34). I need help with the code required to restructure the output due to my lack of PHP knowledge.

You need to know which IDs you will look for, considering you have an array of ids :

$attachmentIds = [55,32,34];

You can then loop trough them with the foreach function and perform the same thing as what you did :

foreach ($attachmentIds as $id) {
    $image_attributes = wp_get_attachment_image_src( $id );
    if( $image_attributes ) {
        echo '<img src="'. $image_attributes[0] .'" width="' . $image_attributes[1] . '" height="'. $image_attributes[2] .'">';
    }
}
