* Add PHp Session extension auto instrumentation hooks * Run Session testcase in CI * Fix 8.4 CI * Add empty Unit test folder * Add more session functions to the list * Addressed review comments * redacted cookie value from span * Refactored code to use switch statement * Updated session-destroy instrumentation to ad sessionid and name * Using return value to set the span status * removed exception handler since session function doesnt throw exception in any case * Storing cookie keys in array and setting only error status * Removed unnecessary check around cookie value --------- Co-authored-by: github-actions[bot] <github-actions[bot]@users.noreply.github.com>

# PHP Session Auto-instrumentation for OpenTelemetry
2+
3+
This package provides auto-instrumentation for PHP's native session functions.
4+
5+
## Installation
6+
7+
```bash
8+
composer require open-telemetry/opentelemetry-auto-session
9+
```
10+
11+
## Usage
12+
13+
The instrumentation hooks into PHP's native session functions to provide tracing capabilities. It automatically creates spans for session operations like `session_start()` and `session_destroy()`.
14+
15+
```php
16+
<?php
17+
// Make sure to initialize the OpenTelemetry SDK before using sessions
18+
// ...
19+
20+
// Register the PHP Session instrumentation
21+
\OpenTelemetry\Contrib\Instrumentation\PhpSession\PhpSessionInstrumentation::register();
22+
23+
// Now any session operations will be automatically traced
24+
session_start();
25+
// ... your code ...
26+
session_destroy();
27+
```
28+
29+
## Spans and Attributes
30+
31+
### session.start
32+
33+
When `session_start()` is called, a span named `session.start` is created with the following attributes:
34+
35+
- `code.function_name`: The function name (`session_start`)
36+
- `php.session.options.*`: Any options passed to `session_start()`
37+
- `php.session.id`: The session ID (if session was successfully started)
38+
- `php.session.name`: The session name (if session was successfully started)
39+
- `php.session.status`: Either "active" or "inactive"
40+
- `php.session.cookie.*`: Session cookie parameters
41+
42+
### session.destroy
43+
44+
When `session_destroy()` is called, a span named `session.destroy` is created with the following attributes:
45+
46+
- `code.function_name`: The function name (`session_destroy`)
47+
- `php.session.id`: The session ID (if available)
48+
- `php.session.name`: The session name (if available)
49+
50+
### session.write_close
51+
52+
When `session_write_close()` is called, a span named `session.write_close` is created with the following attributes:
53+
54+
- `code.function.name`: The function name (`session_write_close`)
55+
- `php.session.id`: The session ID (if available)
56+
- `php.session.name`: The session name (if available)
57+
58+
### session.unset
59+
60+
When `session_unset()` is called, a span named `session.unset` is created with the following attributes:
61+
62+
- `code.function.name`: The function name (`session_unset`)
63+
- `php.session.id`: The session ID (if available)
64+
- `php.session.name`: The session name (if available)
65+
66+
### session.abort
67+
68+
When `session_abort()` is called, a span named `session.abort` is created with the following attributes:
69+
70+
- `code.function.name`: The function name (`session_abort`)
71+
- `php.session.id`: The session ID (if available)
72+
- `php.session.name`: The session name (if available)
