Note: For version 3.0 and higher, refer to this information about the New Relic PHP install script and license key settings in the PHP INI file.

The agent has two parts, a PHP extension and a local proxy daemon. Follow the appropriate installation instructions carefully to make sure you have accounted for both.

Note: As part of the installation process, change the default application name to a meaningful name.

For standard installations, see:

For other types of PHP installations, see PHP agent installation: Non-standard PHP.


After installing the PHP agent, configure the settings for both the agent and the proxy daemon, and then restart Apache or your alternate web dispatcher as applicable. For more information, see:

Sample phpinfo() File: If data does not appear on your New Relic APM dashboard within a few minutes after configuring both the PHP agent and the proxy daemon, check the New Relic section of your phpinfo() file to verify that New Relic is installed.
