variable variable

[violent j]

hello all,

does anybody know how to do something like this??

$method = "GET";
$var = $_$method["var"];

when i do it exactly like this, i get an unexpected T_VARIABLE error

tnx in advance

Are you trying to do this...




$method['get'] = "GET"

$var = $$method['get'];



NOTE:

$var = $_$method IS WRONG (parse error, unexpected T_VARIABLE, blah, blah, blah)

$var = $$method IS RIGHT (variable variable)

[violent j]

nope, won't work either ... i'm using it in this function, maybe it'll get a little more clear

function _GET ($var, $method="_GET") {

if (IsSet ($$method[$var])) {
$retVal = $$method[$var];
} else {
$retVal = "";
}

return $retVal;

} // End function _GET

you can use $_REQUEST (contains any $_POST, $_COOKIE, and/or $_GET data) instead of trying to figure out which method was used

What's the point in re-inventing the wheel, anyway?

hmm ... i'll try the $_REQUEST var

well, the point is, instead of putting something like this on top of each page:

if (IsSet ($_GET["action"])) {
$action = $_GET["action"];
} else {
$action = "";
}

i would then to do this:

$action = _GET ("action"); or
$action = _GET("action","POST"); if it was a post-var

you can shorthand it like this:<?php
foreach($_GET as $key => $value)
{
$$key = $value;
}
?>so, if you have $_GET['action'] after the loop you can get the value like this: $action, instead of $_GET['action']

yeah, i know, but then maybe i get some variables i don't want, and maybe screw my script.

if i use your code, i could just as well enable register_globals

but tnx for your reply :)
