Unable to use the get_excerpt function in wordpress

I am new to wordpress and php. I am trying to get the excerpt of a post retrieved using foreach in wordpress. I am trying to display all the posts on a page but I dont want to display the whole content I want only excerpt. I am able to displat the title but unable to get the excerpt. I have tried: $excerpt = get_post_excerpt($post),$excerpt = get_the_excerpt($post);, $excerpt = $post->the_excerpt() please also tell me if iam missing some basics.

here is my full code 

<?php
	function some_code()  {  
// query
    $query = 'orderby=date&order=asc&posts_per_page=-1';
    $wpq = new WP_Query($query);


    $posts = $wpq->get_posts();
    foreach($posts as $post)
    {
		$link = get_permalink($post);
		echo "<a href='$link'><h3>{$post->post_title}</h3></a>";
		 $excerpt = get_the_excerpt($post); 
		echo "$excerpt";
    }

	}
?>

An easy solution compatible with your code would be to use setup_postdata($post); inside your foreach loop, which makes all the post related data available:

$query = 'orderby=date&order=asc&posts_per_page=-1';
$wpq = new WP_Query($query);
$posts = $wpq->get_posts();
foreach($posts as $post)
{
     setup_postdata($post);
     $excerpt = get_the_excerpt($post);
     echo $excerpt;
}

More about setup_postdata() can be found here.

Try this also if that doesn't work, I think using a traditional loop instead of foreach is a better approach:

$query = array('orderby' => 'date', 'order' => 'asc', 'posts_per_page' => '-1');
$wpq = new WP_Query($query);
if($wpq->have_posts()){
    while($wpq->have_posts()){
        $wpq->the_post();
        the_excerpt();
    }
}

Or you can use a function called wp_trim_words:

echo wp_trim_words( $post->post_content );
