How can PHP developers ensure the correct handling of search queries and pagination to prevent blank pages or incorrect results?

To ensure the correct handling of search queries and pagination in PHP, developers should validate user input, sanitize input data to prevent SQL injection attacks, and properly implement pagination logic to display the correct results on each page. 

// Validate and sanitize search query
$search_query = isset($_GET['search']) ? htmlspecialchars($_GET['search']) : '';

// Implement pagination logic
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$per_page = 10;
$offset = ($page - 1) * $per_page;

// Perform search query with pagination
$query = "SELECT * FROM table WHERE column LIKE '%$search_query%' LIMIT $per_page OFFSET $offset";
// Execute query and display results
