How can one optimize a PHP query to search for multiple terms in various table columns efficiently?

When searching for multiple terms in various table columns in PHP, one way to optimize the query is to use the SQL `LIKE` operator with wildcards (%) to search for each term individually in the columns. This allows for more flexibility in the search criteria and can improve performance compared to using multiple `OR` conditions. 

<?php
// Assuming $searchTerms is an array of terms to search for
$searchTerms = ['term1', 'term2', 'term3'];

// Construct the WHERE clause for the query
$whereClause = '';
foreach ($searchTerms as $term) {
    $whereClause .= "column1 LIKE '%$term%' OR column2 LIKE '%$term%' OR ";
}
$whereClause = rtrim($whereClause, ' OR ');

// Execute the query with the constructed WHERE clause
$query = "SELECT * FROM table_name WHERE $whereClause";
// Execute the query and fetch results
// $result = mysqli_query($connection, $query);
// while ($row = mysqli_fetch_assoc($result)) {
//     // Process the results
// }
?>
