PHP file listing multiple file extensions

Question

Here is my current code:

$files = glob("*.jpg");

This works fine. However, I am wanting to list other image types, such as .png, gif etc.

Can I please have some help to modify this above code to get it working. I have tried the following with no success:

$files = glob("*.jpg","*.png","*.gif");

$files = glob("*.jpg,*.png,*.gif);

And other variations...

Answer 1

$files = glob("*.{jpg,png,gif}", GLOB_BRACE);
