is there a php code for this

[rsg]

is there a code in php similiar to asp's code to check whether or not the current page's url matches a certain string (extremely usefull for conditional includes)

or is there something that will give me the refering url in a string so i can block out certain requests for a page if the refering page doesn't match what i want?

Your probally wanting $PHP_SELF and $HTTP_REFERER

Hope this helps

I'm new to php but I use the following code snippet to determine the current filename (under Apache only, I believe):

<?php

/***************************************
** Get environment variables.
***************************************/

$full_path = getenv("REQUEST_URI");

/***************************************
** Evaluate base path's existence,
** get filename and compensate for
** hidden index.html file.
***************************************/

$dot_pos = strpos($full_path, ".");
if ($dot_pos == false) {
$base = $full_path;
$page_file = "index.html";
}
else {
$base = dirname($full_path);
$page_file = basename($full_path);
}

?>

$PHP_SELF refers to the current filename. It is commonly used when you will call the file from itself to pass variables so that a user can change the filename without having to change the code.

$HTTP_REFERER doesn't seem to work, is this compatible with php3?
