getting value from the url

[Bahy]

I want to edit a row in my database which has the testid field , so i did a list of all testid in the first page ( named edittest.php ) which contains anchors that has the format like this :http://localhost/edit.php?testid=A01 .
"A01" is a value of the testid in my database , and i have done this , the problem i want help from you all is that what do i write in the edit.php file to get the value of the tesid from the url of the edit.php file ( in the example above is "A01") and then passing the value to the variable $testid to do a query ?
I guess i have to use the $HTTP_POST_VARS but don;t know how to deal with it .
Anyone have done this please help me .

In older PHP:
$testid = $PHP_GET_VARS['testid'];

In even older PHP $testid is already available.

In modern PHP:
$testid = $_GET['testid'];

Ummm.. hate to be a spoil-sport but its not $PHP_GET_VARS but

$HTTP_GET_VARS['testid']

That was that uneasy feeling that I had something wrong...

or turn register_globals off.

that way you can use $testid
without the other stuff


but the other way is better.!

uhh no that is backwards. you should never turn them ON.

and it doesn't matter how old the php is, well to a point, but if register_globals are ON then the variable is all you need. but if OFF you need $_GET.

and $testid is available in any version of php, just depends on if register_globals is ON or OFF

and $HTTP_GET_VARS['testid'] is deprecated and shouldn't be used.

Turning register_globals on is discouraged for security reasons. But in very old PHP there wasn't a register_globals option AFAIK.
