How can PHP code be optimized to avoid repetitive queries and reduce script bloating?

To avoid repetitive queries and reduce script bloating in PHP, you can use caching techniques such as storing query results in variables or in a cache system like Memcached or Redis. This way, if the same query needs to be executed multiple times, you can simply retrieve the cached result instead of running the query again. 

// Example of caching query results to avoid repetitive queries
$cacheKey = 'cached_query_results';

// Check if the cached result exists
if (!($result = getFromCache($cacheKey))) {
    // Run the query if the result is not cached
    $result = runQuery();
    
    // Store the query result in cache
    saveToCache($cacheKey, $result);
}

// Use the $result variable for further processing
echo $result;
