How can PHP's explode function be used to shorten blog entries and create dynamic anchors for "Read More" links?

To shorten blog entries and create dynamic anchors for "Read More" links using PHP's explode function, you can split the content at a certain point (e.g., after a certain number of characters) and then append an anchor tag with the remaining content as the "Read More" link. 

<?php
$content = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.";
$limit = 100;

if(strlen($content) > $limit){
    $shortened_content = substr($content, 0, $limit);
    $remaining_content = substr($content, $limit);
    echo $shortened_content . "<a href='#' id='readmore'>Read More</a>";
    echo "<div id='remaining_content' style='display:none;'>".$remaining_content."</div>";
} else {
    echo $content;
}
?>
