Question

Using PHP, is there a way to test if the browser is accessing a certain page?

For example, I have a header file called header.php which is being pulled into a couple different pages. What I want to do is when I go to a different page, I want to append certain variable to the title.

Example.

Inside header.php:

<?php 

$titleA = " Online Instruction";
$title B = "Offline";
?>

<h2>Copyright Info: <?php if ('onlineinstruction'.php) echo $titleA; ?> </h2> 

edit: also if you believe there is a simpler way to do this, let me know!

You can use $_SERVER['REQUEST_URI'], $_SERVER['PHP_SELF'], or __FILE__ depending on your version of PHP and how you have your code setup. If you are in a framework it may have a much more developer-friendly function available. For example, CodeIgniter has a function called current_url()

Per PHP Docs:

$_SERVER[‘REQUEST_URI’]: The URI which was given in order to access
this page; for instance, ‘/index.html’.

$_SERVER[‘PHP_SELF’]: The filename of the currently executing script,
relative to the document root. For instance, $_SERVER[‘PHP_SELF’] in a
script at the address http://example.com/test.php/foo.bar would be
/test.php/foo.bar. The __ FILE__ constant contains the full path and
filename of the current (i.e. included) file. If PHP is running as a
command-line processor this variable contains the script name since
PHP 4.3.0. Previously it was not available.
