PHP マニュアル: Calls callbacks for pending operations

説明

void zookeeper_dispatch()

The zookeeper_dispatch function calls the callbacks passed by operations like Zookeeper::get or Zookeeper::exists.

警告

Since version 0.4.0, this function must be called manually to achieve asynchronous operations. If you want that to be done automatically, you also can declare ticks at the beginning of your program.

After PHP 7.1, you can ignore this function. This extension uses EG(vm_interrupt) to implement async dispatch.

パラメータ

この関数にはパラメータはありません。

戻り値

値を返しません。

エラー / 例外

This method emits PHP warning when callback could not be invoked.

});

    sleep(1);
    zookeeper_dispatch();
}
?>

例2 zookeeper_dispatch example #2

Declare ticks.

<?php
declare(ticks=1);

$client = new Zookeeper();
$client->connect('localhost:2181');
$client->get('/zookeeper', function() {
    echo "Callback was called".PHP_EOL;
});
while(true) {
    sleep(1);
}
?>
