HTTP remote file download

HTTP remote download file fopen ("http://www.xxxx.com/1.txt", "r"); // txt, xml can open
Fopen ("http://www.xxxx.com/1.php", "r"); // Only HTML-related content can be viewed, and PHP code cannot.
Fopen ("./1.php"," r "); // you can see all the content locally.

How can I remotely open all content in the PHP file?

Fopen ("ftp://www.xxxx.com/1.php", "r ");

Put data in the session

Fopen ("ftp://www.xxxx.com/1.php", "r ");
If the moderator goes to fopen through http or url, only the content that the browser can parse can be obtained?

Http will start the php parser! Don't you even know?
