This Heroku buildpack enables the ddtrace PHP extension.

• This buildpack requires the heroku-buildpack-datadog buildpack. Follow the instructions there.

To add this buildpack to your project, run the following:

heroku buildpacks:add --app <your-app-name> https://github.com/SpeedCurve-Metrics/heroku-buildpack-php-ddtrace.git

Make sure to add this buildpack after the PHP buildpack, as a PHP binary is needed to run the installer.

This buildpack accepts several config vars. All of them are optional:

• DD_RELEASE - The release version of dd-trace-php to download. Uses latest release if omited.
• DD_INSTALLER_URL - The URL to the datadog-setup.php to be used (to be found on the dd-trace-php release page).
• DD_PROFILING_ENABLED - Set to a non empty value, this will install and enable the profiling extension.
• DD_APPSEC_ENABLED - Set to a non empty value, this will install and enable the appsec extension.

Note: In case DD_RELEASE is omited, this will always install the latest version.
