What is the difference between using opendir/readdir and glob() for listing directory contents in PHP?

Using opendir/readdir and glob() are two different methods for listing directory contents in PHP. opendir/readdir allows for more control over the iteration process and can be used to filter files based on specific criteria. On the other hand, glob() is a simpler and more concise way to list directory contents, as it returns an array of file paths matching a specified pattern. Here is an example of how to use glob() to list directory contents: 

$files = glob('/path/to/directory/*');
foreach($files as $file) {
    echo $file . PHP_EOL;
}
