Question

If I enter the following into the browser:

   http://domain.com/script.php?1234 

And script.php has the following script:

   $key=array_keys($_GET);    echo $key[0]; 

The output will be:

   1234 

(I’m trying to do away with the ugly ?r=1234 and if this works, it will be perfect.)

My question is, is this officially correct or it’s poor programming?

Answer 1

You could as well do

echo $_SERVER['QUERY_STRING'] 

As for creating friendly URLs, there are better ways to do it.

See e.g.: $_GET and URL Rewriting for PHP
