How can the use of the range() function in PHP lead to unexpected results when generating URLs for images in a folder?

When using the range() function in PHP to generate URLs for images in a folder, it can lead to unexpected results because the range() function creates an array of numbers starting from the first parameter to the second parameter. If the folder does not have images with sequential filenames, the generated URLs may point to non-existent images. To solve this issue, you can use the glob() function to get an array of all image files in the folder and then iterate over them to generate the URLs. 

$folder = 'images/';
$imageFiles = glob($folder . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);

foreach ($imageFiles as $image) {
    echo '<img src="' . $image . '" alt="Image">';
}
