What are some common issues that may arise when using wordwrap with $_POST variables?

When using wordwrap with $_POST variables, a common issue that may arise is that the wordwrap function may not work as expected if the input string contains special characters or HTML tags. To solve this issue, you can use the htmlspecialchars function to escape any special characters before applying the wordwrap function. 

$input_text = htmlspecialchars($_POST['input_text']);
$wrapped_text = wordwrap($input_text, 50, "<br>");
echo $wrapped_text;
