Pre-Defined Variable For Calling PHP File.

[eros]

[PHP]//page1.php
<?php
include('pagebase.php');
?>

//pagebase.php
<?php
echo __CALLING_FILE__; // outputs the previous php file. 'page1.php'
?>[/PHP]

I dont know the equivalent of __CALLING_FILE__. Please let me know on how to determine the previous file or the calling file.

What language is __CALLING_FILE__ from...? And what is it that you are trying to do?

__CALLING_FILE__ is not a PHP code.. I put that for example... I am searching for similar functionality... a Pre-Defined of PHP that gives the parent or the calling php file...in order to determine who was called the pagebase.php.. and use it into conditional statement for different processes..

[PHP]<?php
//pagebase.php
switch ( __CALLING_FILE__ ) {
case "index.php":
//codes here if index.php is the calling php file.
break;
case "page1.php":
//codes here if page1.php is the calling php file.
break;
case.............
//codes here if ????.php is the calling php file.
break;..........
}
?>[/PHP]

Yeah, that's not possible, but it's halfway senseless, anyway.

You do know that you can attach a query string when including a file, right? Maybe you could add this to your includes:

[php]include 'foo.php?callingFile=' . basename(__FILE__);[/php]

Then check $_GET['callingFile'] in the included file.

Yes that's it, but unfortunately i got an error Failed opening required
[PHP]require_once '../phpbase.php?callingFile=' . basename(__FILE__);[/PHP]

[PHP]<?php
include '../phpbase.php?var=1';
//.................
?>[/PHP]

Then you'll need to create a more sensible program flow. What is it that you are trying to do....?

You could try using defined constants.

[php]// page1.php
define('PAGE1', true);[/php]

[php]// page2.php
if(defined('PAGE1'))
{
...
}[/php]

In page1.php was done well but in page2.php, when passed through to if(defined('PAGE1')), "Constant PAGE1 already defined" was noticed. Returns false value.

Sounds like you made a typo.
