parameter.defaultValue

Code example

<?php declare(strict_types = 1);

function greet(int $count = "hello"): void
{
	echo $count;
}

Why is it reported?

The default value of a parameter is incompatible with the parameter's declared type. In the example above, the parameter $count is declared as int, but its default value is "hello", which is a string.

How to fix it

Change the default value to match the declared type:

-function greet(int $count = "hello"): void
+function greet(int $count = 0): void
 {
 	echo $count;
 }

Or change the parameter type to match the default value:

-function greet(int $count = "hello"): void
+function greet(string $count = "hello"): void
 {
 	echo $count;
 }
