# InvalidScalarArgument
|
|
|
|
Emitted when a scalar value is passed to a method that expected another scalar type.
|
|
|
|
This is only emitted in situations where Psalm can be sure that PHP tries to coerce one scalar type to another.
|
|
|
|
In all other cases `InvalidArgument` is emitted.
|
|
|
|
```php
|
|
<?php
|
|
|
|
function foo(int $i) : void {}
|
|
function bar(string $s) : void {
|
|
if (is_numeric($s)) {
|
|
foo($s);
|
|
}
|
|
}
|
|
```
