Ben sadece bu yüzden ben bunu öğrenmek için bir sürü var dün gece memcache (d) ile oynamaya başladı

Bu kod diğer memcache fonksiyonlarını kullanarak olmalıdır eğer o ya da ne yaptığını yapmanın iyi bir yolu olup olmadığını bilmek isteyen am

Önbellek ben mysql içerik oluşturmak sonra var ve sayfada mysql sonucu göstermek sonra önbelleğe ayarlayın yoksa ben bir şey bir önbellek versiyonunu göstermek istiyorum, sonra bir sonraki sayfa yük, onun önbelleğini kontrol eder ve bunun olduğunu görmek Orada, bu yüzden bunu gösterecektir.

This code seems to do the trick but there are several different memcache functions should I be using other ones to accomplish this?

<?PHP
$memcache= new Memcache();
$memcache->connect('127.0.0.1', 11211);

$rows2= $memcache->get('therows1');
if($rows2 == ''){
    $myfriends = findfriend2(); // this function gets our array from mysql
    $memcache->set('therows1', $myfriends, 0, 30);
    echo '<pre>';
    print_r($myfriends); // print the mysql version
    echo '</pre>';
}else{
    echo '<pre>';
    print_r($rows2); //print the cached version
    echo '</pre>';
}
?>

/**
 * A function to do ensure only one thing can update a memcache at a time.
 *
 * Note that there are issues with the $expiryTime on memcache not being
 * fine enough, but this is the best I can do. The idea behind this form
 * of locking is that it takes advantage of the fact that
 * {@link memcache_add()}'s are atomic in nature.
 *
 * It would be possible to be a more interesting limiter (say that limits
 * updates to no more than 1/second) simply by storing a timestamp or
 * something of that nature with the lock key (currently stores "1") and
 * not deleitng the memcache entry.

 * @param $memcache memcache the memcache object
 * @param $key string the key to do the update on
 * @param $updateFunction mixed the function to call that accepts the data
 *  from memcache and modifies it (use pass by reference).
 * @param $expiryTime integer time in seconds to allow the key to last before
 *  it will expire. This should only happen if the process dies during update.
 *  Choose a number big enough so that $updateFunction will take much less
 *  time to execute.
 * @param $waitUTime integer the amount of time in microseconds to wait before
 *  checking for the lock to release
 * @param $maxTries integer maximum number of attempts before it gives up
 *  on the locks. Note that if $maxTries is 0, then it will RickRoll forever
 *  (never give up). The default number ensures that it will wait for three
 *  full lock cycles to crash before it gives up also.
 * @return boolean success or failure
