How can I ensure that the search keyword logging functionality in my PHP application is efficient and optimized for performance?

To ensure that the search keyword logging functionality in your PHP application is efficient and optimized for performance, you can implement a batch processing mechanism to handle logging in bulk rather than logging each search keyword individually. This will reduce the number of database queries and improve overall performance.

// Batch process search keyword logging
function logSearchKeywords($keywords) {
    $batchSize = 100; // Set batch size
    $chunks = array_chunk($keywords, $batchSize); // Split keywords into batches

    foreach ($chunks as $chunk) {
        $placeholders = rtrim(str_repeat('(?,?),', count($chunk)), ','); // Generate placeholders for batch insert
        $values = [];
        foreach ($chunk as $keyword) {
            $values[] = $keyword;
            $values[] = date('Y-m-d H:i:s'); // Add timestamp
        }

        $sql = "INSERT INTO search_logs (keyword, timestamp) VALUES $placeholders";
        $stmt = $pdo->prepare($sql);
        $stmt->execute($values);
    }
}

// Example usage
$keywords = ['keyword1', 'keyword2', 'keyword3', 'keyword4']; // Array of search keywords
logSearchKeywords($keywords);
