You already have the right code — AddType text/plain php, which will make Apache treats PHP files (or files where the name ends with .php) as plain-text files.
But assuming the following:
You have WordPress installed in the
/var/www/htmldirectory.The PHP files are uploaded to the default
uploadsfolder in WordPress (wp-content/uploads).
If you set the directory to /var/www/html/wp-content/uploads as in:
<Directory /var/www/html/wp-content/uploads> AddType text/plain php </Directory> You'd get the results you wanted — only PHP files in the uploads folder will be treated as plain-text files, and not all PHP files in the /var/www/html directory. This explains the issue with "To open the post http://home.local/wp/?p=4785, I got the following output", where that output is the code in the file /var/www/html/index.php. I mean, you used <Directory /var/www/html>, which makes Apache treats the index.php file as a plain-text file, instead of executing the PHP code in the file.
ALTERNATE METHOD: Use the .htaccess file.
Particularly if you can't edit or have no access to the Apache's configuration (.conf) file.
Create
.htaccessin theuploadsfolder, if it's not already there.Then add
AddType text/plain phpin that file.
Additional Notes
I want to see the content in
testme.php, click it, pop up new window
I'm sure you can do that or already have the code/solution, but an easy way, is just add target="_blank" to the attachment/file link.. or with JavaScript, you can use window.open().
And you must take full security measures since allowing people to upload PHP files could harm your site and/or your site users.

What are you trying to accomplish? It seems you're trying to get a hyperlink that displays the contents of a PHP file. WordPress posts are stored in the database. So when you say "publish it", what are you talking about? The database entry that refers to a WordPress post, or the PHP file? If all you want on the screen is the unexecuted contents of the PHP file, you shouldn't be publishing a WordPress "post". What is contained in the post? If you're talking about putting a PHP file as the CONTENT of a post, that would be a different thing too. Probably the easiest way to display the content of a PHP file is to just rename it to a text file.
myFile.php => myFile.php.txt
