random file name

[john_zakaria]

now i am getting all images in a file using the function glob

$files = glob("../images/gallery/".$x."thumbnails/*.jpg") 

after that i store it in an array

 foreach ($files as $value) 

all that i need is to make the $value to produce random value from the array produced by foreach function...

when i echo the image i want it to be random.. thats all that i need

Glob already returns an array so I'm not sure what you mean by "after that I store it in an array". If you just want to get a random item from the array you can use array_rand:

$files = glob("../images/gallery/".$x."thumbnails/*.jpg");
echo $files[array_rand($files)]; 

If you are doing this in a loop, I would do something like:

$files = glob("../images/gallery/".$x."thumbnails/*.jpg");
shuffle($files);
foreach ($files as $file) {
    //...
}
