How can developers monitor and manage the usage and performance of Memcache in PHP applications to prevent issues related to query size and caching?

Developers can monitor and manage the usage and performance of Memcache in PHP applications by setting a limit on the query size and implementing proper caching strategies. This can help prevent issues related to large query sizes overwhelming the cache and impacting performance. 

// Set a limit on the query size
$max_query_size = 1024; // 1 KB

if(strlen($query) > $max_query_size){
    // Handle the query size exceeding the limit
    // Log an error or take appropriate action
} else {
    // Proceed with caching the query
    $memcache = new Memcache;
    $memcache->connect('localhost', 11211);

    $result = $memcache->get($query);

    if($result === false){
        // Execute the query and cache the result
        $result = // Execute the query here

        $memcache->set($query, $result, MEMCACHE_COMPRESSED, 3600); // Cache for 1 hour
    }

    // Use the cached result
    echo $result;
}
