What steps should be taken to ensure the target upload directory exists before attempting to move files in PHP?

To ensure the target upload directory exists before attempting to move files in PHP, you can use the `is_dir` function to check if the directory exists. If it doesn't exist, you can create the directory using the `mkdir` function. 

$targetDir = 'uploads/';

if (!is_dir($targetDir)) {
    mkdir($targetDir, 0777, true);
}

// Now you can safely move files to the target directory
