zookeeper_dispatch

Calls callbacks for pending operations

说明

void zookeeper_dispatch ( void )

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

Caution

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.

错误/异常

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

范例

示例 #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();
}
?>

示例 #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);
}
?>
