以下memcached对象的大小是否会在到达代码末尾时发生变化?

<?php
$m = new Memcached();
$m->addServer('localhost', 11211);

$m->set('array', array(11, 12, 13, 14, 15, 16, 17, 18, 19, 20)); //Size in memory is X

$m->set('array', array(11, 12)); //Size in memory is ?

?>

是的,它会减少内存

使用memory_get_usage();打印内存使用情况,您将看到参考

 $m->set('array', array(11, 12, 13, 14, 15, 16, 17, 18, 19, 20));

 $memory = memory_get_usage();
 echo $memory ."<br>"; // it print 235368

 $m->set('array', array(11, 12));

 $memory = memory_get_usage();
 echo $memory ."<br>"; // it print 235504
