[PHP] 'Dynamic variable name' ?

[RedPillow]

This is something I've managed to do so far:

Code: PHP [Select]

1. function generateMap {
2.         $i = 0;
3.                 $openMap = fopen("map/map_1-1.txt", "r");
4.                         while (!feof($openMap)) {
5.                                 $line = fgets($openMap, 1024);
6.                                         $map = str_split($line);

The problem is, that I want to name the array $map like $map$i  or $map + $i...
So that it's like $map1 = blah, $map2 = blah, $map3 = blah ...

Do you get me?
How do I do that?

Why not use arrays instead?

[RedPillow]

Whaat?

I want to get every line of the text-file.
Then spilt those lines to arrays called map1, map2, map3 ... where each character of the line is one cell of an array.
But how do I name the $map differently after every loop?

like $map$i or somrthing?

Do as the man says, use an array.

[RedPillow]

What do you mean?
Aren't I using arrays when splitting the lines to an array?

[f0dder]

Instead of your idea of "$map$i", you'd use multi-dimension arrays, or an array of arrays... like

Code: PHP [Select]

1. $ubermap[i] = str_split($line);

Thanks!
It's working now as so:
(Btw, any 'better' way to thank like reputation + etc. ?)

Code: PHP [Select]

1. $i = 0;
2.         $openMap = fopen("map/map_1-1.txt", "r");
3.                 while (!feof($openMap)) {
4.                         $line = fgets($openMap);
5.                         $map[$i] = str_split($line);
6.                         $i++;
7.                 }
8. fclose($openMap);
9.  
10. for ($row = 0; $row <= 13; $row++)
11. {
12.     for ($col = 0; $col <= 13; $col++)
13.     {
14.                 if ($map[$row][$col] == 'X') {
15.                         echo "<img src = 'img/wall/X.jpg'/>";}
16.                 elseif ($map[$row][$col] == 'G') {
17.                         echo "<img src = 'img/terrain/G.jpg'/>";}
18.     }
19. }

No reputation system, Eternal Gratefulness will also work nicely. But if there was a reputation system in place, f0dder would obviously be off the scale anyways

Or a (small) donation to the person that helped you out so nicely

Ath: obviously, I'm embarrassed I didn't think of that first!
