PHP $_GET['string'+$var] - Is this possible? -


php code far.

echo $sender = isset($_get['s']) ? $_get['s'] : "null"; echo $receiver = isset($_get['r']) ? $_get['r'] : "null"; echo $timestamp = isset($_get['t']) ? $_get['t'] : "0"; echo "<br/>"; echo $stotalitems = isset($_get['si']) ? intval($_get['si']) : 0; echo $rtotalitems = isset($_get['ri']) ? intval($_get['ri']) : 0; echo "<br/>";   ($i = 0; $i < $stotalitems; $i++) {     echo $input = isset($_get['si'+$i]) ? urldecode($_get['si'+$i]) : "null";     if ($input == "null")         continue;      $input = explode(":", $input);     var_dump($input);  }

what i'm trying dynamically grab variable. i'm sending multiple requests, , contain same data, small differences. - question simple though. doesn't work i'm thinkin should in mind.

$_get['si'+$i];

in mind, should turn into..

$_get['si1'];

can done? or going have figure out way this? doing.. i'm sending multiple requests.. in following order basically..

http://dummy.com/integrate.php?s=me&r=you&t=3425&si=1&ri=2&si0=item:1:2&ri0=item:2:1&ri1=item:3:4

i'm trying make dynamically possible, send more 1 "item," in there identifier telling system, how many items there each sender, , receiver. loop goes through each sender & receivers' items, , separates item, 3 values. name, id, , amount. problem, code, isn't grabbing item @ all. correct, assume, can't use $_get method, , variable together?

yes can use dynamic variables along $_get, problem use . (period) concatenation not +.
