What are common issues when copying and pasting content from MS Word into a PHP application?

When copying and pasting content from MS Word into a PHP application, common issues include the presence of special characters, formatting tags, and non-standard characters that can break the layout or functionality of the application. To solve this issue, you can use PHP's strip_tags() function to remove any HTML tags and special characters from the pasted content before displaying it on the application.

$pasted_content = $_POST['pasted_content']; // Assuming the pasted content is submitted through a form

$clean_content = strip_tags($pasted_content);

echo $clean_content;
