What are the potential pitfalls of defining variables within PHP image creation scripts?

Defining variables within PHP image creation scripts can lead to potential issues with variable scope and readability. To avoid these pitfalls, it is recommended to define variables outside of the image creation script and pass them as parameters to the functions responsible for creating the image. 

// Define variables outside of the image creation script
$imageWidth = 500;
$imageHeight = 300;
$backgroundColor = imagecolorallocate($image, 255, 255, 255);

// Create image function with parameters
function createImage($width, $height, $bgColor) {
    $image = imagecreate($width, $height);
    imagefill($image, 0, 0, $bgColor);
    // Add more image creation code here
    return $image;
}

// Call the createImage function with defined variables
$image = createImage($imageWidth, $imageHeight, $backgroundColor);
