<?php
  echo number_format(10.363, 1, thousands_separator: " ");

->

ERROR: InvalidNamedArgument - 3:31 - Parameter $thousands_separator does not exist on function number_format
ERROR: TooManyArguments - 3:6 - Too many arguments for number_format - expecting 2 but saw 3

number_format function signature (https://www.php.net/manual/ru/function.number-format.php):

number_format(
    float $num,
    int $decimals = 0,
    ?string $decimal_separator = ".",
    ?string $thousands_separator = ","
): string

I found these snippets:

<?php

echo number_format(10.363, 1, thousands_separator: " ");

Psalm output (using commit 832fc35):

ERROR: InvalidNamedArgument - 3:31 - Parameter $thousands_separator does not exist on function number_format

ERROR: TooManyArguments - 3:6 - Too many arguments for number_format - expecting 2 but saw 3

Working on this, the simple fix is fairly easy, number_format was just a bit weird before PHP 8.0.
