# PossiblyUnusedParam
|
|
|
|
Emitted when `--find-dead-code` is turned on and Psalm cannot find any uses of a particular parameter in a public/protected method
|
|
|
|
```php
|
|
<?php
|
|
|
|
class A {
|
|
public function foo(int $a, int $b) : int {
|
|
return $a + 4;
|
|
}
|
|
}
|
|
|
|
$a = new A();
|
|
$a->foo(1, 2);
|
|
```
|
|
|
|
Can be suppressed by prefixing the parameter name with an underscore:
|
|
|
|
```php
|
|
<?php
|
|
class A {
|
|
public function foo(int $a, int $_b) : int {
|
|
return $a + 4;
|
|
}
|
|
}
|
|
```
