[RESOLVED] opendir sort by random?

trendMM

Hi everyone,

I'm using this opendir code to read all the images from a directory and put them into a php file which is then loaded into flash for a flash slideshow. Works great as is right now but I would like to make it so it will randomize the files found in the folder rather than sort by name which is does now.

I've looked at the sort command and I'm lost on how to use it and code it into my existing code. Can someone please lend me a hand. Here's a snipplet of my current code...

if ($handle = opendir($folder)) {
   while (false !== ($file = readdir($handle))) { 
     if ($file != "." && $file != "..") { 
       echo '<image><file>'.$file.'</file><caption><![CDATA[NO COMMENT...]]></caption></image>'; 
     } 
   }
  closedir($handle); 
}

Thanks in advance!

Try this

if ($handle = opendir($folder)) {
   while (false !== ($file = readdir($handle))) { 
     if ($file != "." && $file != "..") { 
       $my_file[] = $file; 
     } 
   }
  closedir($handle); 
}

srand((float)microtime() * 1000000);
shuffle($my_file);

foreach ($my_file as $file) {
echo "<image><file>$file</file><caption><![CDATA[NO COMMENT...]]></caption></image>";
}

thanks a lot! it works great. i really appreciate your help. i'll check out the php.net site and see if i can figure out what the functions you did actually do and get a better understanding of what's going on. thanks again!

i save all the files into an array in the while-statement. Then i use the shuffle() function to "shake" the array to get the content in a random order. That's basically it 🙂

Sorry for my por english!
