$_GET, $_Post....?

90Nz0

I hear I have to use this $get and $post stuff now, and before I do, I would like to know what it is.

I belive it works like the following

// URL = index.php?var1=Hello&var2=World
echo $var1." ".$var2; // This will echo " "
echo $_get['var1']." ".$_get['var2']; // this will echo "Hello World"

also, if you have a form, where the two fields are called "var1" and "var2", and send that form to index.php, you'll have to use the following

echo $var1." ".$var2; // This will echo " "
echo $_post['var1']." ".$_post['var2']; // this will echo "Hello World"

Of corse this is with the defaults of PHP.

Please tell me it isn't true and why have they done this.

Thanks folx,

Paul.

// Edit, what's the difference between 'echo' and 'print' ?

Hi,
it's true, but you can configure this in php.ini file: if register_globals are on you can use directly $var1 & $var2 instead of $GET/$POST["var1"] & $GET/$POST["var2"].

From my php.ini:
"Global variables are no longer registered for input data (POST, GET, cookies, environment and other server variables). Instead of using $foo, you must use you can use $REQUEST["foo"] (includes any variable that arrives through the request, namely, POST, GET and cookie variables), or use one of the specific $GET["foo"], $POST["foo"], $COOKIE["foo"] or $_FILES["foo"], depending on where the input originates.

Also, you can look at the import_request_variables() function.
Note that register_globals is going to be depracated (i.e., turned off by default) in the next version of PHP, because it often leads to security bugs. Read http://php.net/manual/en/security.registerglobals.php for further
information."

see you

Bugger.

Does that mean that I can ignore $GET, $POST, $COOKIE and $FILES, and just use $_REQUEST ?

That's soo firkin' annoying.

At lest you can use .HTTACCESS to turn it on/off.

Would the following be proper useage on both types of script (ovbously iyou could use a form to give the same security issues)

$var1 = $_REQUEST['var1'];
$var2 = $_REQUEST['var2'];

echo $var1." ".$var2; //

Cheers for your help,

Paul
