You know how to split up an array, so just do the same thing again. And as soon as you utter that nasty little "do the same thing again" the word, "recursion" should pop into your head. You are in luck though, I have a million things to do, so I procrastinated and wrote you a little recursive function that will handle 1 to 4 dimensional arrays. For example, you can do this: <? for($i=0;$i<3;$i++) { for($j=0; $j<3;$j++) { $arr[$i][$j] = "${i}_x_${j}"; } } $session["two"] = $arr; // 3-dimensional $session["zero"] = "123"; // 1-dimensional $session["one"] = array( "first_index" => "Hello", "second_index" => "World"); // 2-dimensional $ts = Split_Array($session); echo $ts; ?> Now, the above mess should spit out a massive string that looks like this: session[arr][0][0]=0_x_0&session[arr][0][1]=0_x_1&session[arr][0][2] =0_x_2&session[arr][1][0]=1_x_0& session[arr][1][1]=1_x_1&session[arr][1][2]=1_x_2&session[arr][2][0] =2_x_0&session[arr][2][1]=2_x_1& session[arr][2][2]=2_x_2&session[test]=123&session[one][first_index] =Hello&session[one][second_index ]=World& That`s quite a mouthful, but as far as I can tell from your question, this is what you are trying to generate. So, we need an extremely magical recursive Split_Array() function. And here it is: <? function Split_Array($array,$first="",$second="",$third="") { while(list($key,$val) = each($array)) { if(is_array($val)) $ret .= Split_Array($array[$key] , (strlen($first) ? $first:$key), (strlen($second) ? $second:(strlen($first)?$key:"")), (strlen($third) ? $third:(strlen($second)?$key:""))); else { $ret .= "session"; if(strlen($first)) $ret .= "[$first]"; if(strlen($second)) $ret .= "[$second]"; if(strlen($third)) $ret .= "[$third]"; $ret .= "[$key]=$val&"; } } return $ret; } ?> I bet a few people will have to chew on this one for a while to try to figure out what the heck I am doing. Basically it is a recursive function with optional arguments. Each level of recursion gets another argument so we can keep track of the indices since by the time we nest deep enough to get to the final value we have to have all the indices that took us there. This one is probably a keeper, so the example page maintainers out there should probably do something with this one. If nothing else, it shows that PHP isn`t only for the weekend web warrior. You can write some pretty tricky stuff. Well, relatively speaking anyway. It can get a lot trickier than this, as well. One thing to note here is that n-dimensional arrays like this are not going to get parsed correctly if you set a cookie to the value of the above. So, I suspect your effort may be in vain, although you don`t mention what you plan on using this for. | |||||
