Functions

queue()

queue(\GuzzleHttp\Promise\TaskQueueInterface  $assign = null) : \GuzzleHttp\Promise\TaskQueueInterface

Get the global task queue used for promise resolution.

This task queue MUST be run in an event loop in order for promises to be settled asynchronously. It will be automatically run when synchronously waiting on a promise.


while ($eventLoop->isRunning()) {
    GuzzleHttp\Promise\queue()->run();
}

Parameters

\GuzzleHttp\Promise\TaskQueueInterface

$assign

Optionally specify a new queue instance.

inspect()

inspect(\GuzzleHttp\Promise\PromiseInterface  $promise) : array

Synchronously waits on a promise to resolve and returns an inspection state array.

Returns a state associative array containing a "state" key mapping to a valid promise state. If the state of the promise is "fulfilled", the array will contain a "value" key mapping to the fulfilled value of the promise. If the promise is rejected, the array will contain a "reason" key mapping to the rejection reason of the promise.

Parameters

\GuzzleHttp\Promise\PromiseInterface

$promise

Promise or value.

unwrap()

unwrap(iterable<\GuzzleHttp\Promise\PromiseInterface>  $promises) : array

Waits on all of the provided promises and returns the fulfilled values.

Returns an array that contains the value of each promise (in the same order the promises were provided). An exception is thrown if any of the promises are rejected.

Parameters

iterable<\GuzzleHttp\Promise\PromiseInterface>

$promises

Iterable of PromiseInterface objects to wait on.

all()

all(mixed  $promises, bool  $recursive = false) : \GuzzleHttp\Promise\PromiseInterface

Given an array of promises, return a promise that is fulfilled when all the items in the array are fulfilled.

The promise's fulfillment value is an array with fulfillment values at respective positions to the original array. If any promise in the array rejects, the returned promise is rejected with the rejection reason.

Parameters

mixed	$promises	Promises or values.
bool	$recursive	If true, resolves new promises that might have been added to the stack during its own resolution.

some()

some(int  $count, mixed  $promises) : \GuzzleHttp\Promise\PromiseInterface

Initiate a competitive race between multiple promises or values (values will become immediately fulfilled promises).

When count amount of promises have been fulfilled, the returned promise is fulfilled with an array that contains the fulfillment values of the winners in order of resolution.

This promise is rejected with a {@see \GuzzleHttp\Promise\AggregateException} if the number of fulfilled promises is less than the desired $count.

Parameters

int	$count	Total number of promises.
mixed	$promises	Promises or values.

any()

any(mixed  $promises) : \GuzzleHttp\Promise\PromiseInterface

each()

each(mixed  $iterable, callable  $onFulfilled = null, callable  $onRejected = null) : \GuzzleHttp\Promise\PromiseInterface

Given an iterator that yields promises or values, returns a promise that is fulfilled with a null value when the iterator has been consumed or the aggregate promise has been fulfilled or rejected.

$onFulfilled is a function that accepts the fulfilled value, iterator index, and the aggregate promise. The callback can invoke any necessary side effects and choose to resolve or reject the aggregate if needed.

$onRejected is a function that accepts the rejection reason, iterator index, and the aggregate promise. The callback can invoke any necessary side effects and choose to resolve or reject the aggregate if needed.

Parameters

mixed	$iterable	Iterator or array to iterate over.
callable	$onFulfilled
callable	$onRejected

each_limit()

each_limit(mixed  $iterable, int|callable  $concurrency, callable  $onFulfilled = null, callable  $onRejected = null) : \GuzzleHttp\Promise\PromiseInterface

Like each, but only allows a certain number of outstanding promises at any given time.

$concurrency may be an integer or a function that accepts the number of pending promises and returns a numeric concurrency limit value to allow for dynamic a concurrency size.

Parameters

mixed	$iterable
int\|callable	$concurrency
callable	$onFulfilled
callable	$onRejected
