How can the number of database queries be minimized in PHP scripts to enhance performance and reduce script runtime?

To minimize the number of database queries in PHP scripts, you can use techniques like caching query results, using JOINs to combine multiple queries into one, and optimizing queries to retrieve only the necessary data. This can enhance performance by reducing the load on the database server and decreasing script runtime. 

// Example of minimizing database queries by caching query results
$cache_key = 'query_results';
if(!($results = getFromCache($cache_key))) {
    $results = runDatabaseQuery();
    saveToCache($cache_key, $results);
}
// Use $results data here
