What methods can be used in PHP to check if a specific folder exists before attempting to read its contents?

To check if a specific folder exists in PHP before attempting to read its contents, you can use the `is_dir()` function. This function checks if a directory exists and is a directory. If the folder exists, you can then proceed to read its contents using functions like `scandir()` or `glob()`. 

$folderPath = 'path/to/folder';

if (is_dir($folderPath)) {
    // Folder exists, proceed to read its contents
    $files = scandir($folderPath);
    
    // Loop through files
    foreach ($files as $file) {
        echo $file . "<br>";
    }
} else {
    echo "Folder does not exist.";
}
