What are some best practices for structuring PHP queries to search for multiple terms in different table columns effectively?

When searching for multiple terms in different table columns in PHP queries, it is best practice to use the SQL WHERE clause with the OR operator to search for each term separately. This allows you to search for multiple terms across different columns effectively. Additionally, using prepared statements can help prevent SQL injection attacks. 

// Assume $term1 and $term2 are the search terms
$term1 = "term1";
$term2 = "term2";

// Assume $conn is the database connection

$stmt = $conn->prepare("SELECT * FROM table_name WHERE column1 LIKE ? OR column2 LIKE ?");
$stmt->bind_param("ss", $searchTerm1, $searchTerm2);

$searchTerm1 = "%$term1%";
$searchTerm2 = "%$term2%";

$stmt->execute();
$result = $stmt->get_result();

// Fetch and display results
while ($row = $result->fetch_assoc()) {
    // Display search results
}
