What is the best practice for counting the contents of multiple text files in a folder using PHP?

When counting the contents of multiple text files in a folder using PHP, the best practice is to loop through each file, read its contents, and increment a counter for each file. This can be achieved by using functions like scandir() to get a list of files in a directory and file_get_contents() to read the contents of each file. 

$folder = 'path/to/folder';
$files = scandir($folder);
$totalCount = 0;

foreach($files as $file) {
    if(is_file($folder . '/' . $file) && pathinfo($file, PATHINFO_EXTENSION) == 'txt') {
        $content = file_get_contents($folder . '/' . $file);
        $count = str_word_count($content);
        $totalCount += $count;
    }
}

echo "Total word count of all text files in the folder: " . $totalCount;
