Getting all variables

alirezaok

every time i want to write the script i force to get all variables from previous page. like as:

$t1=$_REQUEST['t1'];
$a5=$_REQUEST['a5'];
$s3=$_REQUEST['s3'];
$w8=$_REQUEST['w8'];
....

is there any way to get all variables from previous page and save in variable? like as:

foreach($_REQUEST as $k => $v)
	{
    $k=$_REQUEST[$k];

}

but i think $k=$_REQUEST[$k]; is not correct. what is soloution?

thanks

Well, you are not "forced" to get them all. You are allowed to use the $_REQUEST elements directly in your script -- you don't have to assign them to scalar variables.

But if you want to do so, you can use the [man]extract[/man] or [man]import_request_variables[/man] functions. If you choose to use either of them, I strongly suggest with each that you make use of the option to add a prefix, so that you can sure there is not any "crashing" between the variable names they create and other variables in your script.

PS: unless it is intentionally ambiguous in your script, it is generally more secure to specify $POST or $GET or $COOKIE rather than $REQUEST, as depending on the variables_order configuration setting, you may not get the value you are expecting.
