zookeeper_dispatch

(PECL zookeeper >= 0.4.0)

zookeeper_dispatchCalls callbacks for pending operations

Descrierea

zookeeper_dispatch ( ) : void

The zookeeper_dispatch() function calls the callbacks passwd by operations like Zookeeper::get() or Zookeeper::exists().

Precauţie

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.

Erori/Excepții

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

Exemple

Example #1 zookeeper_dispatch() example #1

Dispatch callbacks manually.

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

Example #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);
}
?>
