What are some alternatives to the scandir() function for listing files in a directory in PHP?

The scandir() function in PHP can be slow and memory-intensive when dealing with directories containing a large number of files. To address this issue, you can use alternatives such as glob() or readdir() functions to list files in a directory more efficiently. 

// Using glob() function to list files in a directory
$files = glob('/path/to/directory/*');
foreach($files as $file) {
    echo $file . "\n";
}

// Using readdir() function to list files in a directory
$dir = opendir('/path/to/directory');
while(false !== ($file = readdir($dir))) {
    if($file != '.' && $file != '..') {
        echo $file . "\n";
    }
}
closedir($dir);
