Variable inside $_GET

[Eruondo]

I'm trying to write a little snippet of code, and I've encountered a problem. What I'm trying to do, is to put a variable with a value inside the $_GET, e.g:

 

$b = 1;
$c = $_GET['data{$b}'];

 

And later I use a while loop to auto increment $b + 1 for so and so many times. My problem is, I can't get this to work! It simply doesn't read the variable, no matter what I try. Does anyone have any suggestions on how to fix this? Thank you very much.

Any one of these should work:

$c = $_GET['data' . $b];
$c = $_GET["data$b"];

what i think he is trying to do is this

$b = array('1a', '2b', '3c', '4d', '5e'); //put the data into an array
$c = $_GET['data-'.implode(',', $b)]; // make the array a string and add "data-" before it

//then to get the info
$data=explode('-', $c); //makes $c into an array with data as $c[0] and your data string as $c[1] (to add more data just add "-" then your string) 
$data=explode(',', $data[1]); // remakes the origanal array from the string

echo $data[0]; //returns 1a

this is not tested but hope it helps :)

lol i just saw what i wrote lack of sleep and a 14 hour shift does hell for my coding :P

it should be

$b = array('1a', '2b', '3c', '4d', '5e'); //put the data into an array

$_GET['data]=implode(',', $b); // make the array a string and assign it ot $_GET['data']

$c=$_GET['data'];

//then to get the info

$data=explode('-', $c); //makes $c into an array with data as $c[0] and your data string as $c[1] (to add more data just add "-" then your string)

$data=explode(',', $data[1]); // remakes the origanal array from the string

echo $data[0]; //returns 1a

lol I'm also wondering how you got this problem to solve from looking at his topic... Nothing is said about arrays, 1a 2b etc., or the format of his data... :P

yes but it is a better way to pass info thro varables rather then making 20 difftrent $_GET varables

[Zeggy]

I don't think so...

You have the added processing/time penalty of having to implode/explode variables, compared to using GET variables normally.

Still, when faced with this situation it would be better to not use GET variables at all...

Thanks both of you, that worked, :) Sorry, I forgot to answer, :P
