[SOLVED] Check if file is being viewed in browser?

[LemonInflux]

Hello, I was trying to think of a way to check if a file is being viewed in a browser, or if it's being included by a script.

 

How is this done? I have no ideas :S

Just put in the script a mail function that emails you everytime it is called up...

 

Or make a db insertion...

No, I mean like this (yay pseudo code ):

 

if(is_being_viewed_in_browser) {

  do this;

} else {

  do that;

}

 

How do I do this? I was looking at this:

 

if(basename(__FILE__) == basename($_SERVER['PHP_SELF'])) {

  do this;

} else {

  do that;

}

 

But surely then if both files are called index.php, this would say they are the same file (even if one is /index.php, and the other is /folder/index.php)?

That is correct, but why would you name a file index.php if its sole purpose was to be used as an included file? Name it something more usefull.

I'll explain a little more about my project..

 

I'm developing a site traffic monitor.

 

The root page is located in /sm/meter/index.php

 

If you view this page in your browser, you will get a control panel, statistics, graphs or whatever, etc etc.

If you include this page, the code will monitor the page you've included.

 

So as well as being an include, it is also a web page, and it would probably be convenient to call it index.php.

As well as this, I don't know what the user will be calling the pages they use it on, so I'd like a fool-proof method if possible.

[trq]

Unfortunately, there is no fool proof method of finding out whether a page was called via a call to include or directly via the browser.

Is there a way of using __FILE__ and $_SERVER['SCRIPT_FILENAME'] (and replacing the / with \)?

[trq]

Actually, thats an idea. Maybe...

 

if (__FILE__ == $_SERVER['SCRIPT_FILENAME']) {
  // file caled directly
} else {
  // file included.
}

 

Will get you what you want?

[LemonInflux]

C:/xampp/htdocs/index.php is $_SERVER['SCRIPT_FILENAME'];

C:\xampp\htdocs\index.php is __FILE__;

 

Would this work..

 

<?php

if (__FILE__ == str_replace("/", DIRECTORY_SEPARATOR, $_SERVER['SCRIPT_FILENAME'])) {
  // file caled directly
} else {
  // file included.
}

?>

 

I'm using directory separator because I'm guessing / and \ wouldn't work cross-platform? Or am I wrong?

[trq]

Just use...

 

<?php

 

if (__FILE__ == str_replace("/", "\\", $_SERVER['SCRIPT_FILENAME'])) {

  // file caled directly

} else {

  // file included.

}

 

?>

[LemonInflux]

Great! It seems to work just fine

 

Thanks very much, I'll be sure to keep this for future use as well
