Does it work?

[Superian]

Could someone please give me an idea about how to check the following script to see if its working properly? Thanks!

 

<?php
function unset_register_globals() {
  if (ini_get('register_globals')) {
    foreach ($GLOBALS as $key => $value) {
      if (!in_array($key, array('_ENV' => 1, '_GET' => 1, '_POST' => 1, '_COOKIE' => 1, '_FILES' => 1, '_SERVER' => 1, '_REQUEST' => 1, 'GLOBALS' => 1))) {
        unset($GLOBALS[$key]);
      }
    }
  }
}
?>

Test it. If you see nothing, create some checks that will verify the data the code is looking for has been found, or has not.

You can use a counter on the foreach to print which "revolution" of the loop it is on when and if it unsets $Globals.

 

 

Adding $x = 1; after the first if statement, and: x++;echo $x; after unset $globals should do the trick.

Good luck.

 

And you could always  simply add: echo $Globals[$key]; inside the second if statement.

Woops, ignore that.

 

Just add an else statement to the if.

 

}else { echo "IF was false!\n" }

That is because your syntax is wrong.

 

In php, the else statment takes no arguements, that is what the else if statment is for, but for this purpose just change that part to:

 

<?php
function unset_register_globals() {
  if (ini_get('register_globals')) {
    foreach ($GLOBALS as $key => $value) {
      if (!in_array($key, array('_ENV' => 1, '_GET' => 1, '_POST' => 1, '_COOKIE' => 1, '_FILES' => 1, '_SERVER' => 1, '_REQUEST' => 1, 'GLOBALS' => 1))) {
        unset($GLOBALS[$key]);
      } else {
			print "Unset";
		}
    }
  }
}
unset_register_globals();
?>

?>

 

It doesn't display any output still! Any help please!

Check what ini_get('register_globals') is returning.

 

echo ini_get('register_globals');

 

But might it not be simpler to just do:

$_POST=array();

$_GET=array();

$_FILES=array();

...

etc, for the ones you need?
