# Stackify PHP Logger

Guide on setting up Stackify's **Standalone PHP Logger** to track application logs and errors.

## Installation with Linux Agent

This is the suggested installation option, offering the best logging performance.

### Install **Stackify Linux Agent**

- [Standard](/docs/linux-installation)
- [Docker](/docs/retrace-docker-install)
- [Kubernetes](/docs/retrace-kubernetes-install)

### Install **stackify/logger** module into your project:

```
composer require stackify/logger
```

### Configure **stackify/logger** module

Replace **Application Name** and **Environment Name** with appropriate values.

```
use Stackify\Log\Standalone\Logger;

$logger = new Logger('Application Name', 'Environment Name');
```

## Installation without Linux Agent

This option does not require a **Stackify Linux Agent** to be installed because it sends data directly to Stackify services. It collects log entries in batches, calls curl using the exec function, and sends data to the background immediately `[exec('curl ... &')]`. This will affect the performance of your application minimally, but it requires permissions to call exec inside the PHP script and it may cause silent data loss in the event of any network issues.

### Install **stackify/logger** module into your project:

```
composer require stackify/logger
```

### Configure **stackify/logger** module

Replace **Stackify API Key**, **Application Name** and **Environment Name** with appropriate values.

```
use Stackify\Log\Transport\ExecTransport;
use Stackify\Log\Standalone\Logger;
    
$transport = new ExecTransport('Stackify API Key');
$logger = new Logger('Application Name', 'Environment Name', $transport);
```

#### Optional Settings

**Proxy:** ExecTransport supports data delivery through proxy. Specify proxy using libcurl format: `<[protocol://][user:password@]proxyhost[:port]>`:

```
$transport = new ExecTransport($apiKey, ['proxy' => 'https://55.88.22.11:3128']);
```

**Curl path:** It can be useful to specify `curl` destination path for ExecTransport. This option is set to 'curl' by default.

```
$transport = new ExecTransport($apiKey, ['curlPath' => '/usr/bin/curl']);
```

**Server environment variables** can be added to error log message metadata.

 This will log all system environment variables; do not enable if sensitive information such as passwords or keys are stored this way.

                         

```
$logger = new Logger('Application Name', 'Environment Name', $transport, true);
```
