# PossiblyFalseArgument
|
|
|
|
Emitted when a function argument is possibly `false`, but the function does not expect `false`. This is distinct from a function argument is possibly `bool`, which results in `PossiblyInvalidArgument`.
|
|
|
|
```php
|
|
<?php
|
|
|
|
function foo(string $s) : void {
|
|
$a_pos = strpos($s, "a");
|
|
echo substr($s, $a_pos);
|
|
}
|
|
```
