What are common issues when using opendir to access folders in PHP?

One common issue when using opendir in PHP is forgetting to close the directory handle after reading the contents of the folder. This can lead to resource leaks and potential performance issues. To solve this problem, make sure to always close the directory handle using closedir() after reading the folder contents. 

$dir = opendir('/path/to/folder');

if ($dir) {
    while (($file = readdir($dir)) !== false) {
        // process files
    }

    closedir($dir);
} else {
    echo "Failed to open directory.";
}
