How can one ensure efficient handling of image uploads and processing to avoid memory-related errors in PHP?

To ensure efficient handling of image uploads and processing in PHP to avoid memory-related errors, one can limit the file size of uploads, optimize image processing functions, and use server-side validation to check for valid image types before processing. 

// Limit the file size of uploads
define('MAX_FILE_SIZE', 5 * 1024 * 1024); // 5MB

if ($_FILES['image']['size'] > MAX_FILE_SIZE) {
    die('File size exceeds limit.');
}

// Optimize image processing functions
ini_set('memory_limit', '128M'); // Increase memory limit for image processing

// Server-side validation for image types
$allowed_types = ['image/jpeg', 'image/png', 'image/gif'];

if (!in_array($_FILES['image']['type'], $allowed_types)) {
    die('Invalid image type.');
}

// Process the image
// Add your image processing code here
