Array_Chunk issue in sidebar using shortcode

    I have a shortcode for displaying REST posts and i would like to use the array_chunk function to split into new rows at x number of posts. My code below works fine in pages, posts and in the sidebar. However, since this isn’t a return; the code causes the main div to break out of the text widget and pushes the widget title below it.

    Is there a way to return the output so this can be used effectively in the sidebar?

    if( !empty( $posts ) ) {  
		 
		 echo "<div class='mrp-container'>\n"; 
		 foreach (array_chunk($posts, $a['columns']) as $post) {
			
			echo "<div class='mrp-row'>\n";
			
    		foreach ( $post as $post ) {
				// Make JSON date human readable
				$jsondate = new DateTime( $post->date );
				$humandate = $jsondate->format("F d, Y");
        		echo '<div class="single-mrp-post'.$mrpcolumns.'">' . '<a href="' . $post->link. '" title="'. $post->title->rendered . 
				  PHP_EOL . PHP_EOL. strip_tags($post->excerpt->rendered) .' "><img src="'. $post->swp_thumbnail .'"/><h4 class="mrp-post-title">'. $post->title->rendered . '</h4></a><p class="mrp-post-date">'.$humandate."</p></div>\n";
	
			}
    	echo "</div>\n";
		}
		echo "</div>\n";
		
	 }

    The usual method is to collect output into a single variable which can be returned.

    $output = '';
foreach ( $posts as $post ){
   $output .= /* whatever content using $post created here */;
}
return $output;

    When faced with a a bunch of mixed PHP and HTML from an existing snippet, converting it all to collect into a single variable can be quite an endeavor. Fortunately, there is an alternative. Output Buffering. Start the buffering at the beginning, then use ob_get_contents() to get the buffered content to be returned. No need to alter the output code at all. Don’t forget to end and clean the buffer when you’re done.

    Most graciously appreciate you help with this. That’s exactly what i needed. I added the ob_end_clean(); to the end like you suggested. And everything works perfect, no more breaking out of the widget sidebar. Thanks a million!

    Here’s my final working code:

    ob_start ();
    if( !empty( $posts ) ) {  
		 
	echo "<div class='mrp-container'>\n"; 
	foreach (array_chunk($posts, $a['columns']) as $post) {
			
	echo "<div class='mrp-row'>\n";
			
    	foreach ( $post as $post ) {
	// Make JSON date human readable
	$jsondate = new DateTime( $post->date );
	$humandate = $jsondate->format("F d, Y");
        echo '<div class="single-mrp-post'.$mrpcolumns.'">' . '<a href="' . $post->link. '" title="'. $post->title->rendered . 
	PHP_EOL . PHP_EOL. strip_tags($post->excerpt->rendered) .' "><img src="'. $post->swp_thumbnail .'"/><h4 class="mrp-post-title">'. $post->title->rendered . '</h4></a><p class="mrp-post-date">'.$humandate."</p></div>\n";
	        }
    	echo "</div>\n";
	}
	echo "</div>\n";
	$output = ob_get_contents();
}
ob_end_clean();
return $output;
