$images = glob($folder . '/*.{png,jpg,jpeg,gif}', GLOB_BRACE);
echo json_encode($images);
exit();
}
?>

Answer 1

It seems you have misused the $_GET variable.
I thing you want to just use the string value, ie.:
$folder = 'C:\xampp\htdocs\firstsite';
And note, the exit() terminates whole script after printing the json_encoded string.
So, to make the function reusable change it to get the path as a parameter $folder:
<?php
function findImagesInFolder($folder, $filter = '*.*')
{
// note, here we expect the path does not trail with backslash
$images = glob($folder . '\\' . $filter, GLOB_BRACE);
return json_encode($images);
}
// call the function with actual path to scan:
$path = 'C:\xampp\htdocs\firstsite';
$filter = '{*.png,*.jpg,*.jpeg,*.gif}';
echo findImagesInFolder($path, $filter);
?>
Note: output as [] means empty array encoded to JSON.
