assigning variables!!

[ibo]

hi, i just cant assign values to variables from the address bar.
For example; i am writing an simple echo sentence like below and call it index.php;

<?
echo("the name of the variable=$name1");
?>

and if i write http://localhost/index.php?name1=x

it writes only "the name of the variable=" and when i check that name1 is empty or not i see that its empty. Whats wrong? the answer may be so easy but would you please help me?

<?
echo "the name of the variable=". $_GET['name1'] ."";
?>

thanks, this is working but i still dont understand why i just cant write "$name1"

i mean everytime i use name1 variable inside my code should i have to write $_GET['name1'] instead of writing simply $name1.

Of course you don't always have to use $GET when you assign variables INSIDE your script.
Only use $_GET when you're retrieving variables from an URL.

When you open an url with variables and values (http://www.something.com/index.php?var=val) you're sending the variable with the GET method, then PHP creates an array with all the GET variables.

It's just like when you post a form, the browser then sends the variables and values to the script with the POST method. You can also use the GET method but I don't recommend it.

Try this...

extract($_GET);
echo 'The name of the variable = ' . $name1;
