Problem using Include

hadoob024

I have a file called copywrite.php that contains various copywrite information. Depending on which file calls this file (using the "include" command) I want various sections of the copywrite.php file to execute.

For example, when my intro page calls copywrite.php, I only want certain text to show. However, for every other file that calls copywrite.php, I want other text to show. Is there any command that I can include in my copywrite.php so that I can use some logic to say something like:

if page1 calls copywrite.php then echo "page1 copywrite text"

else if page2 calls copywrite.php then echo "page2 copywrite text"

thanks..

What you could do is to make your copywrite.php one big case statement :

switch ($_SERVER['REQUEST_URI']){

case "/index.php":  $text = "Don't copy my index page";
                               break;

case "/page2.php": $text = "You can copy the blue text on page 2";
                                break;

default:
                                echo "No copyright information for ". $_SERVER['REQUEST_URI'];
                                break;
}

Start out with none of the "case" statements, just the default. Then visit each page and you should see the value of $_SERVER['REQUEST_URI'] for that page. You can then add in the appropriate case statement and retest.

By the way, I think it's "copyright" - as in the "right to copy".

Cool! Thanks a lot. That worked perfectly. Oh yeah, I hadn't even noticed about the misspelling of copyright. I think I had just seen copywriters, and went with copywrite. Oh well, my bad. Thanks for the help!

By the way, what's the difference between $SERVER['PHP_SELF'] and $SERVER['REQUEST_URI']

heheh... copywriters write copy - they're the folks who come up with the snazzy text for advertisements etc

The best way to understand the difference between server variables like that is to try them 🙂 Here's a very quick way to see it in action. (Forgive me if you know this already) Store the following file somewhere on your web tree (ideally in a secure area).

<?php
    phpinfo();
?>

Now, call this page up in your browser - see it how it shows the values of all your variables?

Now call this page up with some GET variables (eg info.php?color=blue&size=medium) see any difference?

Oh, delete that file when you're finished. It's way too helpful to those who want to do bad things to your server.

Oh ok. I see the difference. But it looks like $SERVER["SCRIPT_NAME"] and $SERVER["PHP_SELF"] are the same, right?

I don't actually remember, and I don't have a PHP environment just now to try it out... but they're all explained here

Cool. That's what I was looking for, a comprehensive list. I couldn't figure out what keyword to look under to find this list. Thanks!

enjoy! 🙂

Beware if your webserver runs PHP as cgi because $_SERVER['SCRIPT_NAME'] will probably always say /cgi-system/php.cgi or something similar, always!

Cool. I just checked phpinfo, and it doesn't look like that's what they did. The value of variable $_SERVER["SCRIPT_NAME"] is the name of the script that I called the function from.
