What best practices should be followed when allowing an admin to create a new gallery with specific requirements in PHP?

When allowing an admin to create a new gallery with specific requirements in PHP, it is important to validate the input data to ensure it meets the required criteria. This can include checking for file types, file sizes, and any other necessary conditions. Additionally, it is recommended to sanitize the input data to prevent any potential security vulnerabilities. 

// Example code snippet for creating a new gallery with specific requirements

// Validate input data
if ($_FILES['image']['type'] != 'image/jpeg' || $_FILES['image']['size'] > 5000000) {
    // Handle error - file type or size does not meet requirements
} else {
    // Sanitize input data
    $galleryName = filter_var($_POST['gallery_name'], FILTER_SANITIZE_STRING);
    
    // Process and save the gallery
    $image = $_FILES['image']['tmp_name'];
    $target = 'uploads/' . basename($_FILES['image']['name']);
    move_uploaded_file($image, $target);
    
    // Save gallery information to database
    // INSERT INTO galleries (name, image) VALUES ('$galleryName', '$target')
}
