Are there best practices for handling image manipulation in PHP to avoid URL file-access restrictions?

When handling image manipulation in PHP, it's important to be aware of URL file-access restrictions that may prevent you from accessing images from external URLs. To avoid this issue, one common approach is to download the image content locally before performing any manipulation. This ensures that the image data is available locally and can be accessed without any restrictions. 

// URL of the image to manipulate
$imageUrl = 'https://example.com/image.jpg';

// Download the image content
$imageContent = file_get_contents($imageUrl);

// Check if the image content was successfully downloaded
if ($imageContent !== false) {
    // Perform image manipulation on the downloaded content
    // For example, resizing, cropping, or applying filters
    // Save or output the manipulated image as needed
} else {
    // Handle the case where the image content could not be downloaded
    echo 'Failed to download image content';
}
