add $var's to new array

[Bungholio]

Hi, thanks for looking,

ok a little bit of nfo before i get to my problem, there are images in 'images/' like so;

39_images01.jpg
39_images02.jpg
40_you are crazy.jpg
40_one-two.jpg

ok so, i have the following code;

function MainPic($GID) {
  $handle = opendir("images");
  while ($file = readdir($handle)) {
    if ($file != "." && $file != ".."){
      $array = split("_",$file);
      if ($array[0] == $GID){
          echo ($file."<br>\n");
      }
    }
  }
  closedir($handle);
} 

so if you can imagine i call my function like;

$GID="39";
MainPic($GID);

then im going to get a list of the images (from above)

39_images01.jpg
39_images02.jpg

right? ... ok, so instead of echoing the files, i would like to put them into an array, because im going to use array_rand in the future to display a random image for the appropriate $GID call .. can any help me with this? I checked the array section on php.net and didnt see any examples of creating arrays with adding $file ..
any ideas?

Thanks a bunch,
Al

You should use array_push() to append values to an array.

You'll find a full list of array commands at http://us3.php.net/array, including array_push() as Jona mentioned, and array_unshift() to prepend values to the beginning of an array.

Well, for what I did, you're welcome. (I'm not gonna speak for pyro, he knows too much as it is. )

lol.. and I always feel bad saying "Your welcome" if I the help was mutually offered, as I feel like I'm saying to the other poster "Hey look, he said thank you, and it must have been to me..." That's just me, I guess... Anyway, for my part, you're welcome...

Didn't mean to bring on the guilt...

hehe... nope, no guilt. Just saying why I didn't acknowledge it.
