# Trace

Not really an issue. Just reports the type of a variable when using
[`@psalm-trace`](../annotating_code/supported_annotations.md#psalm-trace).

```php
<?php

/** @psalm-trace $x */
$x = getmypid();
```

## How to fix

Use it for debugging purposes, not for production
@psalm-trace is now a specific low-level issue, because plain debug print breaks structured output (after #3080) (#3106) 2020-04-09 03:03:05 +02:00			`# Trace`

Make it easier to find how to promote Trace I have used this once before then forgot how to do it, which is a shame because this is super handy. 2023-04-26 21:38:44 +02:00			`Not really an issue. Just reports the type of a variable when using`
