Variables

[shankhar]

A doubt in PHP variables

Assume in one page i'm having a variable named $name and from the previous page i'm getting a value from the form in the variable name $_POST['name'].

i want to know whether both $name and $_POST['name'] are same and rise to conflict in variable names.

And also if there is also a variable getting as GET ($GET['name']) and there is a session variable $SESSION['name']

i want to know that these $name, $POST['name'], $GET['name'], $_SESSION['name'] are same

thanx

If you have sessons started then $GET['name'] and $SESSION['name'] will be the same, the same goes for $POST['name'] and $SESSION['name'] under the same conditions $GET['name'] and $POST['name'] would only be the same if the same information was sent through post as well as get.

$name is not going to pick up the value of any of the $POST, $GET or $SESSION variables, unless you specifically assign them.

Always assuming that register globals is off.

Take a look at http://uk2.php.net/variables.predefined for all the predefined variables.
