# InvalidLiteralArgument
|
|
|
|
Emitted when a literal argument is passed where a variable is expected, such as the first argument of `strpos`, where an explicit `$haystack` is almost always unintended.
|
|
|
|
```php
|
|
<?php
|
|
|
|
function foo(string $s) : void {
|
|
echo strpos(".", $s);
|
|
}
|
|
```
