setting scope

[subhailc]

in js you can say
var a={prop1:value1,prop2:value2};
for(var i in a)this[i]=a[i];
alert(this.prop2)//to get back "value2";
//or
var a=document.getElementsByTagName('*');
for(var i=0;i<a.length;i++)this[a[i].id]=a[i];
//to scope ids as local object refs

how's that functionality work in php? i noticed i don't see 'this' often if at all - effectively just would like to scope the whole of REQUEST to the executing script. triedforeach($_REQUEST as $a)this[$a]=$a;
//and
foreach($_REQUEST as $a=>$b) $a=$b;but probably obviously, no good.

$_REQUEST is a superglobal, that has scope everywhere.

foreach ($_REQUEST as $key=>$val) {
$$key = $val;

}

Would do what (I think) you want...

the extract() function does the same thing (takes an array and assigns the values to variables named after the keys)...

thanks for the reply gjay. i checked out extract and it looks to be just as you said, exactly what i was describing. however for whatever reasons - presuming a setting in the ini or maybe just a question of versions and coincidence, i get no returns on the server i tried where register globals is off (and thus the reason for wanting to grab REQUEST) - although it works great on the servers i tried where register globals are on - and consequently dont need it.

on the foreach - is the double $$ intentional? i tried both ways w/out luck but i can probably attribute that to the server again; before continuing i thought id ask for clarification.

thx again.

The $$ is intentional, referring to a variable with the name of the value of $key.
So, if you have an array ['title'=>'Hello','price'=>'12']
$key will be 'title' on the first iteration, so the variable $title will be set to 'Hello'.
Have you tried using $_POST and/or $_GET instead of $_REQUEST? Might help narrow down the problem...
