PHP code to display substring of current URL?

Question

Hello,

I want to redirect my browser to a PHP page such that when the page loads, it will display to the user a substring of the current URL.

For example, let's say I have a page called substring.php.

My browser forwards me to:

http://www.example.com/substring.php?oauth_token=123456

Is it possible to write some PHP code that will then display to the user, "123456"?

If so, can anyone help me on how to do this?

Thanks!

Answer 1

<?php
  echo $_GET['oauth_token'];
?>

Answer 2

Can't you just use the $_GET superglobal? It stores the contents of the query string part of the URI as an associative array:

echo $_GET['oauth_token'];

Answer 3

All the query parameters in the URL will be inside the superglobal $_GET array, so you could simply do this:

echo $_GET['oauth_token'];

BE forewarned that if you're going to output anything that comes in from a URL (ie. user input), you should make sure to sanitize it properly for output. In this case, htmlspecialchars() would be prudent:

echo htmlspecialchars($_GET['oauth_token']);

Answer 4

You can retrieve the value of oauth_token via the $_GET superglobal array:

echo $_GET['oauth_token'];

Of course you should use caution when outputting data you get as input from a user, but that's how it works in short.
