The AppSignal for PHP library.

Install the latest version of AppSignal with:

composer require appsignal/appsignal-php

First, make sure the build dependencies required to install the OpenTelemetry PHP extension are installed.

On Ubuntu/Debian:

sudo apt-get install gcc make autoconf

or macOS:

brew install gcc make autoconf

Then, install the OpenTelemetry PHP extension using PECL:

pecl install opentelemetry

Finally, enable the extension in php.ini

[opentelemetry]
extension=opentelemetry.so

For more ways to install opentelemetry extension (pie, pickle, Docker), see the Installing the OpenTelemetry extension section in AppSignal Docs.

use Appsignal\Appsignal;

// add a custom instrumentation span to the current trace
Appsignal::instrument('some_event', closure: fn() => sleep(1));

// add a custom instrumentation span to the current trace with data
Appsignal::instrument('some_event', ['region' => 'eu'], closure: fn() => sleep(1));

// customize the name of the trace
Appsignal::setAction('my action'),

// add attributes to the current span
Appsignal::addAttributes([
    'string-attribute' => 'abcdef',
    'int-attribute' => 1234,
    'bool-attribute' => true,
]);

// add tags to the current span
Appsignal::addTags([
    'string-tag' => 'some value',
    'integer-tag' => 1234,
    'bool-tag' => true,
]);

// report a handled exception
Appsignal::setError($exception);

// add metrics
Appsignal::setGauge('my_gauge', 12);
Appsignal::setGauge('my_gauge_with_attributes', 13, ['region' => 'eu']);

Appsignal::addDistributionValue('memory_usage', 50);
Appsignal::addDistributionValue('memory_usage', 70);

Appsignal::addDistributionValue('with_attributes', 10, ['region' => 'eu']);
Appsignal::addDistributionValue('with_attributes', 20, ['region' => 'eu']);
Appsignal::addDistributionValue('with_attributes', 30, ['region' => 'eu']);

Appsignal::incrementCounter('my_counter', 1);
Appsignal::incrementCounter('my_counter', 3, ['region' => 'eu']);

This package uses Composer as the dependency manager. Once you have Composer installed, install all dependencies:

composer install

If you'd rather not install PHP and Composer locally, you can run Composer commands in a Docker container using the scripts/call_composer command:

scripts/call_composer any_composer_command_or_script

Run the following command in the root of this repository to run all PHPUnit tests:

composer test

# or with Docker
scripts/test

or run a single test file:

composer test tests/Path/To/YourTest.php

# or with Docker
scripts/test tests/Path/To/YourTest.php

or a single test case:

composer test --filter testMethodName

# or with Docker
scripts/test --filter testMethodName

This package supports PHP versions >= 8.4. If you want to run tests against a specific version of PHP, pass PHP_VERSION environment variable to the scripts/test command:

PHP_VERSION=8.5 scripts/test

You can run PHPStan anaylzer:

composer lint

# or with Docker
scripts/call_composer lint

or run PHP Coding Standards Fixer:

composer cs                    # check
composer cs:fix                # fix

# or with Docker
scripts/call_composer cs       # check
scripts/call_composer cs:fix   # fix
