Entry

How can I get the URL of the current page that the script is processing?

How can I get the *FULL* URL of the current script, including the URL fraction (.../foo.php#bar)?

There are many predefined variables that contain a lot of information, 
a good way to figure out exactly what you need/want is to make a call 
to phpinfo() in your script (foo.php below):
  http://www.example.com/dir/foo.php?fruit=apple&color=red
A few predefined variables that you'll see:
  PHP_SELF     : /dir/foo.php
  QUERY_STRING : fruit=apple&color=red
  REQUEST_URI  : /dir/foo.php?fruit=apple&color=red
To access these predefined variables, try either:
  // Works since PHP 3
  print $HTTP_SERVER_VARS['PHP_SELF'];
  // Works since PHP 4.1.0
  print $_SERVER['PHP_SELF'];
  // Works if the PHP directive register_globals = on.  
  // Note: The default for this directive is off since
  // PHP 4.2.0
  print $PHP_SELF;
More can be read about reserved and predefined variables here:
  http://www.php.net/manual/en/language.variables.predefined.php
The information after the # in an URL is not available to the server 
hence it won't be available to PHP, only client-side.
