What is the purpose of incrementing a variable when a file exists in PHP code?

When checking if a file exists in PHP, incrementing a variable can be used to keep track of the number of files found that match a certain criteria. This can be useful when processing multiple files and needing to perform different actions based on the number of files found. By incrementing a variable, you can easily count the number of files that meet the specified conditions. 

$directory = '/path/to/directory/';
$filesFound = 0;

foreach (glob($directory . '*.txt') as $file) {
    if (file_exists($file)) {
        // Perform actions on the file
        $filesFound++;
    }
}

echo 'Number of .txt files found: ' . $filesFound;
