What best practices should be followed when implementing a search function with multiple search terms in PHP?

When implementing a search function with multiple search terms in PHP, it is important to properly sanitize and validate the input to prevent SQL injection attacks. Additionally, you should construct the query dynamically based on the search terms provided by the user, using placeholders to bind parameters. Finally, consider implementing pagination to handle large result sets efficiently.

// Assuming $searchTerms is an array of search terms
// Sanitize and validate the input
$searchTerms = array_map('htmlspecialchars', $searchTerms);
$searchTerms = array_map('mysqli_real_escape_string', $searchTerms);

// Construct the query dynamically
$query = "SELECT * FROM table WHERE ";
foreach($searchTerms as $term){
    $query .= "column LIKE '%$term%' AND ";
}
$query = rtrim($query, "AND ");

// Execute the query using prepared statements
$stmt = $mysqli->prepare($query);
$stmt->execute();
$result = $stmt->get_result();

// Implement pagination
// Display the results
