How can the correct variable be passed to mkdir() in PHP to create directories successfully?

To create directories successfully using mkdir() in PHP, you need to ensure that you are passing the correct variable containing the directory path as the first argument to the mkdir() function. This variable should be properly constructed and formatted to represent the desired directory path. Make sure to handle any necessary permissions or error checking to ensure the directory is created successfully. 

$directoryPath = "path/to/new/directory";
// Check if directory doesn't exist
if (!is_dir($directoryPath)) {
    // Create the directory with proper permissions
    mkdir($directoryPath, 0777, true);
    echo "Directory created successfully.";
} else {
    echo "Directory already exists.";
}
