php 文件可以像 html 文件一样在互联网上查看吗？

Question

if I want to view the code of a web page written in html I just need to right click and select view source. Can the same be done with php files so I can learn how certain tasks are being accomplished? Is there a way to hide the code?

Answer 1

Unless the server is very improperly set up, no. Very no.

For example, at the top of my "includes/database.php" file, I have three lines that look like

$host = "localhost";
$username = "myuser";
$password = "mypassword";

You can see why I'd not want that publicly visible...

Answer 2

No, they can't. PHP is a server-side scripting language, the browser never actually sees the php code.

Answer 3

Generally no and I will tell you why.

What happens is that the browser is asking for a file that the web server can serve to the user. The file has the extension .php for example. The web server is setup so whenever he gets a request for a file with that extension he has to run it through PHP first and use the output from PHP as the output to serve the user.

So the user asks for a file, the web server finds it, sees that PHP has to process it first, PHP does and gives the web server the output (whatever it is) and the web server then gives the user that content.

It can happen that the web server is configured in the wrong way and skips the PHP step, so then the user sees pure PHP but this is very rare and usually spotted immediately.

Answer 4

absolutely no way. PHP is processed before being outputted to the browser so its all server side!

Answer 5

Hypertext pre processor is interpreter which understand the code and convert into html form with the help of webserver so it is not able to view on webserver
But on local machine without Webserver we can see the code

Answer 6

如果文件扩展名为 .phps，您只能查看代码
