How can the str_replace function be used to remove unwanted line breaks in PHP forum posts?

When forum posts are submitted by users, they may contain unwanted line breaks that can disrupt the formatting of the content. To remove these unwanted line breaks, the str_replace function in PHP can be used to replace the line breaks with an empty string. This will effectively remove the line breaks from the forum posts and ensure a cleaner presentation of the content. 

// Sample forum post content with unwanted line breaks
$forum_post = "This is a sample forum post with 
unwanted line breaks.";

// Remove unwanted line breaks using str_replace
$clean_forum_post = str_replace(array("\r", "\n"), '', $forum_post);

// Output the cleaned forum post content
echo $clean_forum_post;
