Attempt
=======

[](#attempt)

Retry a PHP callable when an operation fails.

Installation
------------

[](#installation)

```
composer require jord-jd/attempt
```

The package supports PHP 7.1 through current PHP 8.x releases.

Usage
-----

[](#usage)

```
$result = attempt(function () {
    return fetchFromAnUnreliableApi();
})
    ->maxAttempts(5)
    ->withGap(2)
    ->now();
```

`maxAttempts(5)` means at most five total executions, including the first one. Use `maxAttempts(0)`, the default, for no attempt limit. The last exception is available as the previous exception on `MaxAttemptsExceeded`.

### Exponential or custom backoff

[](#exponential-or-custom-backoff)

```
$result = attempt($operation)
    ->maxAttempts(5)
    ->withExponentialBackoff(1, 2.0, 30)
    ->now();
```

Successive delays are 1, 2, 4, and 8 seconds, with later retries capped at 30 seconds. For complete control, return a non-negative integer number of seconds from `withBackoff()`:

```
use Exception;

$result = attempt($operation)
    ->withBackoff(function (int $failedAttempt, Exception $exception): int {
        return min(60, $failedAttempt * 5);
    })
    ->now();
```

Calling `withGap()` after `withBackoff()` switches back to a fixed delay.

### Retry selected exceptions

[](#retry-selected-exceptions)

Do not retry permanent failures:

```
$result = attempt($operation)
    ->retryIf(function (Exception $exception, int $failedAttempt): bool {
        return $exception instanceof TemporaryApiException;
    })
    ->maxAttempts(5)
    ->now();
```

When the predicate returns false, the original exception is rethrown.

### Observe retries

[](#observe-retries)

```
attempt($operation)
    ->onRetry(function (Exception $exception, int $failedAttempt, int $delay): void {
        logger()->warning('Operation failed; retrying', [
            'attempt' => $failedAttempt,
            'delay' => $delay,
            'exception' => $exception,
        ]);
    })
    ->now();
```

The callback runs only when another execution will actually be attempted.

### Time limits and scheduled starts

[](#time-limits-and-scheduled-starts)

```
// Retry until this instant. No execution is started at or after the deadline.
attempt($operation)
    ->until(new DateTimeImmutable('+30 seconds'))
    ->withGap(5)
    ->now();

// Wait until this instant, then begin. A past time starts immediately.
attempt($operation)
    ->at(new DateTimeImmutable('+5 seconds'));
```

If the next configured delay would cross the deadline, Attempt waits only until the deadline and throws `DateTimeExceeded` without starting a late execution.

All configuration methods can be chained. Negative attempt limits or gaps and invalid exponential-backoff values throw `InvalidArgumentException` immediately.
