make three php pages,
each containing the following
apart from the last line
<?php
echo '<pre>';
echo "me: " . __FILE__;
echo $_SERVER["REQUEST_URI"] . "\n";
echo $_SERVER["SCRIPT_NAME"] . "\n";
echo $_SERVER["PHP_SELF"] . "\n";
echo $_SERVER["SCRIPT_FILENAME"] . "\n";
echo "\n\n";
include ( '2.php' );
?>
inside 2.php the last line should be 3.php
and inside 3.php theres no include
you will see that __FILE__ always contains the name of the script it
is in, whether than is included in something else or not.
whereas $_SERVER['SCRIPT_FILENAME'] doesnt change, it returns 1.php
because that is the script your are executing, so you can use it to
find the name of the file that includes the others.
your basic script would be
if( basename($_SERVER['SCRIPT_FILENAME'])=='index.php' )
{
include( 'signature.php' );
}
however if you change your server setup this might not always work, as
you said before hard coding things like this is generally not a good
idea. Instead look at the architecture you are building and see if you
cant handle the whole thing in one function somewhere centrally
located say in /private/appname/functions
this way your life is easier later on.
hope that helps.
