What are common pitfalls when trying to check the contents of a folder in PHP?

Common pitfalls when trying to check the contents of a folder in PHP include not handling errors properly, not verifying if the folder exists before trying to access its contents, and not considering file permissions. To avoid these pitfalls, it's important to use functions like `is_dir()` to check if the folder exists, handle errors using `try-catch` blocks, and ensure that the script has the necessary permissions to access the folder. 

$folderPath = 'path/to/folder';

if (is_dir($folderPath)) {
    $files = scandir($folderPath);
    
    foreach ($files as $file) {
        // Process each file in the folder
        echo $file . PHP_EOL;
    }
} else {
    echo "Folder does not exist.";
}
