Psalm is a static analysis tool for finding errors in PHP applications, built on top of [PHP Parser](https://github.com/nikic/php-parser).
|
||
|
||
It's able to find a [large number of issues](https://github.com/vimeo/psalm/blob/master/docs/issues.md), but it can also be configured to only care about a small subset of those.
|
||
|
||
[Try a live demo](https://psalm.dev/), or install it in your project by following the Quickstart Guide below.
|
||
|
||
## Psalm documentation
|
||
|
||
Documentation is available on [Psalm’s website](https://psalm.dev/docs), generated from the [docs](https://github.com/vimeo/psalm/blob/master/docs) folder.
|
||
|
||
## Quickstart Guide
|
||
|
||
Install via [Composer](https://getcomposer.org/):
|
||
|
||
```bash
|
||
composer require --dev vimeo/psalm
|
||
```
|
||
|
||
Add a config:
|
||
|
||
```bash
|
||
./vendor/bin/psalm --init
|
||
```
|
||
|
||
Then run Psalm:
|
||
|
||
```bash
|
||
./vendor/bin/psalm
|
||
```
|
||
|
||
The config created above will show you all issues in your code, but will emit `INFO` issues (as opposed to `ERROR`) for certain common trivial code problems. If you want a more lenient config, you can specify the level with
|
||
|
||
```bash
|
||
./vendor/bin/psalm --init [source_dir] [level]
|
||
```
|
||
|
||
You can also [learn how to suppress certain issues](https://github.com/vimeo/psalm/blob/master/docs/dealing_with_code_issues.md).
|
||
|
||
## How Psalm Works
|
||
|
||
A basic rundown of Psalm’s internals can be found in [docs/how_psalm_works.md](https://github.com/vimeo/psalm/blob/master/docs/how_psalm_works.md).
