Display some WooCommerce product reviews with limited content length randomly - php

Question

I am making shortcode for reviews Based on WooCommerce: Display some reviews randomly on home page to put on other pages. How can i limit reviews by character numbers, like 100 or 200 characters. SO they will not be too long and fit any page.
I am using following code for reviews now
function get_random_five_stars_products_reviews( $atts ) {
// Extract shortcode attributes
extract( shortcode_atts( array(
'limit' => 5, // number of reviews to be displayed by default
), $atts, 'woo_reviews' ) );
$comments = get_comments( array(
'status' => 'approve',
'post_status' => 'publish',
'post_type' => 'product',
'meta_query' => array( array(
'key' => 'rating',
'value' => '5',
) ),
) );
shuffle($comments);
$comments = array_slice( $comments, 0, $limit );
$html = '<ul class="products-reviews">';
foreach( $comments as $comment ) {
$rating = intval( get_comment_meta( $comment->comment_ID, 'rating', true ) );
$html .= '<li class="review">';
$html .= '<div>'.get_the_title( $comment->comment_post_ID ).'</div>';
if ( $rating > 4 ) $html .= wc_get_rating_html( $rating );
$html .= '<div>' .$comment->comment_content.'</div>';
$html .= "<div>Posted By :".$comment->comment_author." On ".$comment->comment_date. "</div>";
$html .= '</li>';
}
return $html . '</ul>';
}
add_shortcode('woo_reviews', 'get_random_five_stars_products_reviews');

To limit displayed 5 starts reviews with a content that doesn't exceed a specific length (here 100 characters) use the following:
function get_random_five_stars_products_reviews( $atts ) {
// Extract shortcode attributes
extract( shortcode_atts( array(
'limit' => 5, // number of reviews to be displayed by default
'length' => 100, // Limit comments text content lenght
'show_stars' => true, // Or "false" to hide
), $atts, 'woo_reviews' ) );
$comments = get_comments( array(
'status' => 'approve',
'post_status' => 'publish',
'post_type' => 'product',
'meta_query' => array( array(
'key' => 'rating',
'value' => '5',
) ),
) );
shuffle($comments);
$count = 0; // Initializing
$html = '<ul class="products-reviews">';
foreach( $comments as $comment ) {
$content = $comment->comment_content;
if( strlen($content) <= $length && $count < $limit ) {
$rating = intval( get_comment_meta( $comment->comment_ID, 'rating', true ) );
$html .= '<li class="review">';
$html .= '<div>'.get_the_title( $comment->comment_post_ID ).'</div>';
if ( $show_stars ) {
$html .= wc_get_rating_html( $rating );
}
$html .= '<div>' .$content. '</div>';
$html .= "<div>Posted By :".$comment->comment_author." On ".$comment->comment_date. "</div>";
$html .= '</li>';
$count++; // Increase count
}
if ( $count == $limit ) {
break; // Stop the loop
}
}
return $html . '</ul>';
}
add_shortcode('woo_reviews', 'get_random_five_stars_products_reviews');
Code goes in functions.php file of the active child theme (or active theme). It should works.
