# UnusedParam
|
|
|
|
Emitted when `--find-dead-code` is turned on and Psalm cannot find any uses of a particular parameter in a private method or function
|
|
|
|
```php
|
|
<?php
|
|
|
|
function foo(int $a, int $b) : int {
|
|
return $a + 4;
|
|
}
|
|
```
|
|
|
|
Can be suppressed by prefixing the parameter name with an underscore:
|
|
|
|
```php
|
|
function foo(int $_a, int $b) : int {
|
|
return $b + 4;
|
|
}
|
|
```
