Display all meta for a post?

I have a custom meta field for my posts and I’m able to display the value. But it only displays one row. Since I have more than one value I need to display all of them. I know I probably have to do some kind of for or while loop, but I don’t know how to do it.

This is my current code:

$meta_value = get_post_meta( get_the_ID(), 'meta-text', true );

if( !empty( $meta_value ) ) :
    echo $meta_value; 
endif;

How do I change that snippet to display all rows?

To get all rows, don’t specify the key. Try this:

$meta_values = get_post_meta( get_the_ID() );

var_dump( $meta_values );  // so you can see the structure
