How can the PHP glob function be utilized in the context of reading files from a folder?

To read files from a folder in PHP, the glob function can be used to retrieve an array of file paths matching a specified pattern. By using glob with the "*" wildcard to match all files in a folder, we can easily retrieve all file paths for further processing.

$folder_path = "path/to/folder/";
$files = glob($folder_path . "*");

foreach ($files as $file) {
    echo $file . "<br>";
}
