How do I write PHP code with the opening and closing PHP tags in the article textarea during editing so that the it displays properly with tags in the published article? I don't want the PHP code to execute, I just want to show it unaltered in the article so that it stands out from the surrounding text. WordPress inserts a space before the question mark in the opening PHP tag. It sometimes also shortens filenames surrounded by tags, and it adds an extra tag (less-than, forward slash, space, greater than) before the tag.
