php - PHP: Pthread + Memcache の問題

Question

Memcache は、pthread スレッド内では機能しないようです。

次の警告が表示されます。

Warning: Memcache::get(): No servers added to memcache connection in test.php on line 15



   class Test extends Thread {

    protected $memcache;

    function __construct() {
        $this->memcache = New Memcache;
        $this->memcache->connect('localhost',11211 ) or die("Could not connect");
    }

    public function run() {
        $this->memcache->set('test', '125', MEMCACHE_COMPRESSED, 50);
        $val = $this->memcache->get('test');p
        echo "Value $val.";
        sleep(2);
    }

}

$threads = [];
for ($t = 0; $t < 5; $t++) {
    $threads[$t] = new Test();
    $threads[$t]->start();
}

for ($t = 0; $t < 5; $t++) {
