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);

This is just an expansion of @Jeroen answer.

Somethings to keep in mind

'flag' is Important

Since you are using curly brackets, keep in mind GLOB_BRACE required. Without the flag you will get a empty array if items

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

Sorting

This will also help you to sort the files in the way you have written.
The sorting below is based on the order of extensions inside the curly bracket.

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

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

+ Bonus

If you have to list out all the files but without folder, you can use this

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