What are best practices for optimizing image upload and processing workflows in PHP applications?

When optimizing image upload and processing workflows in PHP applications, it is important to validate file types, resize images to an appropriate size, and store them in a secure location. Additionally, using image manipulation libraries like GD or Imagick can help with processing tasks efficiently. 

// Example PHP code snippet for optimizing image upload and processing workflows

// Validate file type
$allowedTypes = ['image/jpeg', 'image/png', 'image/gif'];
if (!in_array($_FILES['image']['type'], $allowedTypes)) {
    die('Invalid file type. Only JPEG, PNG, and GIF files are allowed.');
}

// Resize image
$source = $_FILES['image']['tmp_name'];
$destination = 'uploads/' . $_FILES['image']['name'];
list($width, $height) = getimagesize($source);
$newWidth = 500;
$newHeight = ($height / $width) * $newWidth;
$resizedImage = imagecreatetruecolor($newWidth, $newHeight);
$image = imagecreatefromjpeg($source);
imagecopyresampled($resizedImage, $image, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);
imagejpeg($resizedImage, $destination);

// Store image in secure location
move_uploaded_file($_FILES['image']['tmp_name'], $destination);

// Display success message
echo 'Image uploaded and processed successfully.';
