FFI Environment

A set of API methods for working with the FFI environment.

Requirements

• PHP >= 7.4

Installation

Library is available as composer repository and can be installed using the following command in a root of your project.

$ composer require ffi/env

Usage

Retrieve FFI Status

use FFI\Env\Runtime;

$status = Runtime::getStatus();

Status can be be one of:

• \FFI\Env\Status::NOT_AVAILABLE - Extension not available.
• \FFI\Env\Status::DISABLED - Extension disabled.
• \FFI\Env\Status::ENABLED - Extension enabled and available in any environment.
• \FFI\Env\Status::CLI_ENABLED - Extension available only in CLI SAPI or using a preload.

Checking Availability

use FFI\Env\Runtime;

$isAvailable = Runtime::isAvailable();

In the case that the environment needs to be checked unambiguously, then you can use assertAvailable() method:

use FFI\Env\Runtime;

Runtime::assertAvailable();
// Throws an \FFI\Env\Exception\EnvironmentException in case FFI is not available.

Optimization

To check the environment, it is recommended to use the assert functionality.

use FFI\Env\Runtime;
use FFI\Env\Exception\EnvironmentException;

assert(Runtime::assertAvailable());

// Or using your own assertion error message:
assert(Runtime::isAvailable(), EnvironmentException::getErrorMessageFromStatus());
