Chilkat PHP Extension — Downloads

The latest Chilkat PHP extension (PHP 8.5) for Windows, Linux, Alpine Linux, and macOS. Choose the build that matches your PHP version, operating system, and CPU architecture.

Quick install — one command

Using Composer (any OS) — the package holds the PHP classes, and its installer fetches the matching extension:

composer require chilkat/chilkat
vendor/bin/chilkat-install

Without Composer — Linux, Alpine Linux, macOS:

curl -fsSL https://chilkatdownload.com/php/install-php.sh | sudo sh

Windows (PowerShell):

irm https://chilkatdownload.com/php/install-php.ps1 | iex

The script asks your PHP which version, architecture, and thread-safety it is, downloads the matching build, installs chilkat.so/chilkat.dll and chilkat.php, enables the extension, and runs a test. No need to pick a download from the tables below. In a Dockerfile it is one RUN line — see Docker, Alpine Linux, and CI. See the Linux, macOS and Windows install pages for the options (--dry-run, --php, --uninstall) and the manual steps.

Looking for an older PHP version? This page lists only PHP 8.5. For earlier versions (PHP 5.x through 8.4) and the legacy Linux / CentOS 7 builds, see Chilkat PHP Extension — Older Versions.
