Are there any best practices or guidelines for handling file manipulation functions like imagejpeg in PHP to avoid SAFE MODE Restriction issues?

When dealing with file manipulation functions like imagejpeg in PHP, it is important to be aware of the SAFE MODE Restriction issues that may arise. To avoid these issues, it is recommended to use the correct file permissions and ensure that the directory where the files are being saved has the necessary permissions set.

// Example code snippet to handle imagejpeg function with proper file permissions
$filename = 'image.jpg';
$image = imagecreatefromjpeg('original.jpg');

// Check if the directory has the necessary permissions
if (is_writable(dirname($filename))) {
    // Save the image with imagejpeg function
    imagejpeg($image, $filename);
    echo 'Image saved successfully!';
} else {
    echo 'Error: Directory does not have the necessary permissions';
}
